Given numbers are 642, 931, 451, 487
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 931) = 597702
GCD(642, 931) = ( 642 x 931 ) / 597702
= 642 / 931
= 642
Step2:
LCM(1, 451) = 451
GCD(1, 451) = ( 1 x 451 ) / 451
= 1 / 451
= 1
Step3:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
So, Greatest Common Divisor of 642, 931, 451, 487 is 1
