Given numbers are 125, 661, 855

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

Apply this formula for all numbers.

Step1:

LCM(125, 661) = 82625

GCD(125, 661) = ( 125 x 661 ) / 82625

= 125 / 661

= 125

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 125, 661, 855 is 1
