GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 176) = 27632
GCD(628, 176) = ( 628 x 176 ) / 27632
= 628 / 176
= 628
Step2:
LCM(4, 655) = 2620
GCD(4, 655) = ( 4 x 655 ) / 2620
= 4 / 655
= 4
Step3:
LCM(1, 549) = 549
GCD(1, 549) = ( 1 x 549 ) / 549
= 1 / 549
= 1
So, Greatest Common Divisor of 628, 176, 655, 549 is 1
