Given numbers are 991, 670, 651

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

Apply this formula for all numbers.

Step1:

LCM(991, 670) = 663970

GCD(991, 670) = ( 991 x 670 ) / 663970

= 991 / 670

= 991

Step2:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

So, Greatest Common Divisor of 991, 670, 651 is 1
