Given numbers are 861, 911, 39, 357

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

Apply this formula for all numbers.

Step1:

LCM(861, 911) = 784371

GCD(861, 911) = ( 861 x 911 ) / 784371

= 861 / 911

= 861

Step2:

LCM(1, 39) = 39

GCD(1, 39) = ( 1 x 39 ) / 39

= 1 / 39

= 1

Step3:

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

= 1 / 357

= 1

So, Greatest Common Divisor of 861, 911, 39, 357 is 1
