Given numbers are 786, 646, 943, 457

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

Apply this formula for all numbers.

Step1:

LCM(786, 646) = 253878

GCD(786, 646) = ( 786 x 646 ) / 253878

= 786 / 646

= 786

Step2:

LCM(2, 943) = 1886

GCD(2, 943) = ( 2 x 943 ) / 1886

= 2 / 943

= 2

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 786, 646, 943, 457 is 1
