Steps to Calculate GCD of 647, 190, 643, 907 using LCM Formula
Given numbers are 647, 190, 643, 907
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 190) = 122930
GCD(647, 190) = ( 647 x 190 ) / 122930
= 647 / 190
= 647
Step2:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
Step3:
LCM(1, 907) = 907
GCD(1, 907) = ( 1 x 907 ) / 907
= 1 / 907
= 1
So, Greatest Common Divisor of 647, 190, 643, 907 is 1
