Steps to Calculate GCD of 47, 10, 72, 15 using LCM Formula
Given numbers are 47, 10, 72, 15
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(47, 10) = 470
GCD(47, 10) = ( 47 x 10 ) / 470
= 47 / 10
= 47
Step2:
LCM(1, 72) = 72
GCD(1, 72) = ( 1 x 72 ) / 72
= 1 / 72
= 1
Step3:
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
= 1 / 15
= 1
So, Greatest Common Divisor of 47, 10, 72, 15 is 1
