Given numbers are 403, 572, 655, 321
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 572) = 17732
GCD(403, 572) = ( 403 x 572 ) / 17732
= 403 / 572
= 403
Step2:
LCM(13, 655) = 8515
GCD(13, 655) = ( 13 x 655 ) / 8515
= 13 / 655
= 13
Step3:
LCM(1, 321) = 321
GCD(1, 321) = ( 1 x 321 ) / 321
= 1 / 321
= 1
So, Greatest Common Divisor of 403, 572, 655, 321 is 1
