Steps to Calculate GCD of 16, 61, 72, 38 using LCM Formula
Given numbers are 16, 61, 72, 38
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(16, 61) = 976
GCD(16, 61) = ( 16 x 61 ) / 976
= 16 / 61
= 16
Step2:
LCM(1, 72) = 72
GCD(1, 72) = ( 1 x 72 ) / 72
= 1 / 72
= 1
Step3:
LCM(1, 38) = 38
GCD(1, 38) = ( 1 x 38 ) / 38
= 1 / 38
= 1
So, Greatest Common Divisor of 16, 61, 72, 38 is 1
