Given numbers are 468, 458, 855, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(468, 458) = 107172
GCD(468, 458) = ( 468 x 458 ) / 107172
= 468 / 458
= 468
Step2:
LCM(2, 855) = 1710
GCD(2, 855) = ( 2 x 855 ) / 1710
= 2 / 855
= 2
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 468, 458, 855, 687 is 1
