Given numbers are 991, 641, 87, 286

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

Apply this formula for all numbers.

Step1:

LCM(991, 641) = 635231

GCD(991, 641) = ( 991 x 641 ) / 635231

= 991 / 641

= 991

Step2:

LCM(1, 87) = 87

GCD(1, 87) = ( 1 x 87 ) / 87

= 1 / 87

= 1

Step3:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

So, Greatest Common Divisor of 991, 641, 87, 286 is 1
