Given numbers are 447, 636, 134, 861

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

Apply this formula for all numbers.

Step1:

LCM(447, 636) = 94764

GCD(447, 636) = ( 447 x 636 ) / 94764

= 447 / 636

= 447

Step2:

LCM(3, 134) = 402

GCD(3, 134) = ( 3 x 134 ) / 402

= 3 / 134

= 3

Step3:

LCM(1, 861) = 861

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

= 1 / 861

= 1

So, Greatest Common Divisor of 447, 636, 134, 861 is 1
