Given numbers are 651, 783, 654, 105

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

Apply this formula for all numbers.

Step1:

LCM(651, 783) = 169911

GCD(651, 783) = ( 651 x 783 ) / 169911

= 651 / 783

= 651

Step2:

LCM(3, 654) = 654

GCD(3, 654) = ( 3 x 654 ) / 654

= 3 / 654

= 3

Step3:

LCM(3, 105) = 105

GCD(3, 105) = ( 3 x 105 ) / 105

= 3 / 105

= 3

So, Greatest Common Divisor of 651, 783, 654, 105 is 3
