Given numbers are 861, 749, 667, 416

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

Apply this formula for all numbers.

Step1:

LCM(861, 749) = 92127

GCD(861, 749) = ( 861 x 749 ) / 92127

= 861 / 749

= 861

Step2:

LCM(7, 667) = 4669

GCD(7, 667) = ( 7 x 667 ) / 4669

= 7 / 667

= 7

Step3:

LCM(1, 416) = 416

GCD(1, 416) = ( 1 x 416 ) / 416

= 1 / 416

= 1

So, Greatest Common Divisor of 861, 749, 667, 416 is 1
