Given numbers are 687, 308, 478, 119
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 308) = 211596
GCD(687, 308) = ( 687 x 308 ) / 211596
= 687 / 308
= 687
Step2:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
Step3:
LCM(1, 119) = 119
GCD(1, 119) = ( 1 x 119 ) / 119
= 1 / 119
= 1
So, Greatest Common Divisor of 687, 308, 478, 119 is 1
