Given numbers are 687, 278, 162

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

Apply this formula for all numbers.

Step1:

LCM(687, 278) = 190986

GCD(687, 278) = ( 687 x 278 ) / 190986

= 687 / 278

= 687

Step2:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

So, Greatest Common Divisor of 687, 278, 162 is 1
