Steps to Calculate GCD of 657, 643, 249, 901 using LCM Formula
Given numbers are 657, 643, 249, 901
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 643) = 422451
GCD(657, 643) = ( 657 x 643 ) / 422451
= 657 / 643
= 657
Step2:
LCM(1, 249) = 249
GCD(1, 249) = ( 1 x 249 ) / 249
= 1 / 249
= 1
Step3:
LCM(1, 901) = 901
GCD(1, 901) = ( 1 x 901 ) / 901
= 1 / 901
= 1
So, Greatest Common Divisor of 657, 643, 249, 901 is 1
