Given numbers are 427, 549, 642, 767

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

Apply this formula for all numbers.

Step1:

LCM(427, 549) = 3843

GCD(427, 549) = ( 427 x 549 ) / 3843

= 427 / 549

= 427

Step2:

LCM(61, 642) = 39162

GCD(61, 642) = ( 61 x 642 ) / 39162

= 61 / 642

= 61

Step3:

LCM(1, 767) = 767

GCD(1, 767) = ( 1 x 767 ) / 767

= 1 / 767

= 1

So, Greatest Common Divisor of 427, 549, 642, 767 is 1
