Given numbers are 939, 642, 517, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(939, 642) = 200946
GCD(939, 642) = ( 939 x 642 ) / 200946
= 939 / 642
= 939
Step2:
LCM(3, 517) = 1551
GCD(3, 517) = ( 3 x 517 ) / 1551
= 3 / 517
= 3
Step3:
LCM(1, 455) = 455
GCD(1, 455) = ( 1 x 455 ) / 455
= 1 / 455
= 1
So, Greatest Common Divisor of 939, 642, 517, 455 is 1
