Given numbers are 105, 372, 617, 861

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

Apply this formula for all numbers.

Step1:

LCM(105, 372) = 13020

GCD(105, 372) = ( 105 x 372 ) / 13020

= 105 / 372

= 105

Step2:

LCM(3, 617) = 1851

GCD(3, 617) = ( 3 x 617 ) / 1851

= 3 / 617

= 3

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 105, 372, 617, 861 is 1
