Given numbers are 437, 646, 431, 958

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

Apply this formula for all numbers.

Step1:

LCM(437, 646) = 14858

GCD(437, 646) = ( 437 x 646 ) / 14858

= 437 / 646

= 437

Step2:

LCM(19, 431) = 8189

GCD(19, 431) = ( 19 x 431 ) / 8189

= 19 / 431

= 19

Step3:

LCM(1, 958) = 958

GCD(1, 958) = ( 1 x 958 ) / 958

= 1 / 958

= 1

So, Greatest Common Divisor of 437, 646, 431, 958 is 1
