Given numbers are 498, 861, 642, 451
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(498, 861) = 142926
GCD(498, 861) = ( 498 x 861 ) / 142926
= 498 / 861
= 498
Step2:
LCM(3, 642) = 642
GCD(3, 642) = ( 3 x 642 ) / 642
= 3 / 642
= 3
Step3:
LCM(3, 451) = 1353
GCD(3, 451) = ( 3 x 451 ) / 1353
= 3 / 451
= 3
So, Greatest Common Divisor of 498, 861, 642, 451 is 1
