Given numbers are 286, 143, 646, 790

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

Apply this formula for all numbers.

Step1:

LCM(286, 143) = 286

GCD(286, 143) = ( 286 x 143 ) / 286

= 286 / 143

= 286

Step2:

LCM(143, 646) = 92378

GCD(143, 646) = ( 143 x 646 ) / 92378

= 143 / 646

= 143

Step3:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

So, Greatest Common Divisor of 286, 143, 646, 790 is 1
