Given numbers are 402, 987, 634, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 987) = 132258
GCD(402, 987) = ( 402 x 987 ) / 132258
= 402 / 987
= 402
Step2:
LCM(3, 634) = 1902
GCD(3, 634) = ( 3 x 634 ) / 1902
= 3 / 634
= 3
Step3:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
So, Greatest Common Divisor of 402, 987, 634, 485 is 1
