Given numbers are 321, 645, 537, 251
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(321, 645) = 69015
GCD(321, 645) = ( 321 x 645 ) / 69015
= 321 / 645
= 321
Step2:
LCM(3, 537) = 537
GCD(3, 537) = ( 3 x 537 ) / 537
= 3 / 537
= 3
Step3:
LCM(3, 251) = 753
GCD(3, 251) = ( 3 x 251 ) / 753
= 3 / 251
= 3
So, Greatest Common Divisor of 321, 645, 537, 251 is 1
