Given numbers are 557, 646, 210, 452
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(557, 646) = 359822
GCD(557, 646) = ( 557 x 646 ) / 359822
= 557 / 646
= 557
Step2:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
Step3:
LCM(1, 452) = 452
GCD(1, 452) = ( 1 x 452 ) / 452
= 1 / 452
= 1
So, Greatest Common Divisor of 557, 646, 210, 452 is 1
