Given numbers are 158, 687, 440, 917

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(158, 687) = 108546

GCD(158, 687) = ( 158 x 687 ) / 108546

= 158 / 687

= 158

Step2:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

Step3:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1

So, Greatest Common Divisor of 158, 687, 440, 917 is 1
