Given numbers are 621, 542, 667, 605
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 542) = 336582
GCD(621, 542) = ( 621 x 542 ) / 336582
= 621 / 542
= 621
Step2:
LCM(1, 667) = 667
GCD(1, 667) = ( 1 x 667 ) / 667
= 1 / 667
= 1
Step3:
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
= 1 / 605
= 1
So, Greatest Common Divisor of 621, 542, 667, 605 is 1
