138]. Also, Theorem 2.1 is the analog of the corresponding result for summation of functions with , obtained by Ushiroya [21]. Note that if F is multiplicative, then If , then we deduce the next result. Theorem 2.2 Let be an arbitrary arithmetic function of one variable, let and assume...
Note, gcd(x, y, z) means the greatest common divisor of x, y and z, while lcm(x, y, z) means the least common multiple of x, y and z. Note 2, (1, 2, 3) and (1, 3, 2) are two different solutions. Input First line comes an integer T (T <= 12), telling the number...
Input First line comes an integer T (T <= 12), telling the number of test cases. The next T lines, each contains two positive 32-bit signed integers, G and L. It’s guaranteed that each answer will fit in a 32-bit signed integer. Output For each test case, print one line with ...
(a) 357=5·77=5 (b) 7010=7·5·25·2=7 Sometimes the fraction we use represents how many of a certain thing are successful. For example, if a major league baseball player was at bat 30 times and achieved 12 hits, we could say that he had a hit 1230 of the time. If...

Let S={x_1,x_2,…,x_n}be a set of n distinct positive integers and a≥1 an integer. The matrix having the a-th power(x_i,x_j)~a of the greatest common divisor of x_i and x_j as its i,j-entry is called a-th power greatest common divisor(GCD)matrix defined on S,denote...
This modified LCM-based method is suitable for tissue specific expression analysis of both genes and small RNAs (miRNAs). Isolation of high quality RNA is one of the most important prerequisite for analysis of a small tissue or cell population specific genes expression and their functional ...
every part of us. The eyes, the nose, the mouth..every part of us, every cell, every background, conditions..etc is because of His promise. When we“covenantise”the word of God (promise), it shine our spirit and help us to able to distinguish between spirit. How do we distinguish...
