Steps to Calculate GCD of 247, 787, 138, 641 using LCM Formula
Given numbers are 247, 787, 138, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 787) = 194389
GCD(247, 787) = ( 247 x 787 ) / 194389
= 247 / 787
= 247
Step2:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
Step3:
LCM(1, 641) = 641
GCD(1, 641) = ( 1 x 641 ) / 641
= 1 / 641
= 1
So, Greatest Common Divisor of 247, 787, 138, 641 is 1
