Steps to Calculate GCD of 17, 56, 79, 38 using LCM Formula
Given numbers are 17, 56, 79, 38
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(17, 56) = 952
GCD(17, 56) = ( 17 x 56 ) / 952
= 17 / 56
= 17
Step2:
LCM(1, 79) = 79
GCD(1, 79) = ( 1 x 79 ) / 79
= 1 / 79
= 1
Step3:
LCM(1, 38) = 38
GCD(1, 38) = ( 1 x 38 ) / 38
= 1 / 38
= 1
So, Greatest Common Divisor of 17, 56, 79, 38 is 1
