Given numbers are 678, 537, 667, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 537) = 121362
GCD(678, 537) = ( 678 x 537 ) / 121362
= 678 / 537
= 678
Step2:
LCM(3, 667) = 2001
GCD(3, 667) = ( 3 x 667 ) / 2001
= 3 / 667
= 3
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 678, 537, 667, 621 is 1
