Given numbers are 286, 707, 638, 130

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

Apply this formula for all numbers.

Step1:

LCM(286, 707) = 202202

GCD(286, 707) = ( 286 x 707 ) / 202202

= 286 / 707

= 286

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 286, 707, 638, 130 is 1
