Given numbers are 643, 500, 764, 557
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 500) = 321500
GCD(643, 500) = ( 643 x 500 ) / 321500
= 643 / 500
= 643
Step2:
LCM(1, 764) = 764
GCD(1, 764) = ( 1 x 764 ) / 764
= 1 / 764
= 1
Step3:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
So, Greatest Common Divisor of 643, 500, 764, 557 is 1
