Given numbers are 649, 641, 557, 659
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 641) = 416009
GCD(649, 641) = ( 649 x 641 ) / 416009
= 649 / 641
= 649
Step2:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
Step3:
LCM(1, 659) = 659
GCD(1, 659) = ( 1 x 659 ) / 659
= 1 / 659
= 1
So, Greatest Common Divisor of 649, 641, 557, 659 is 1
