Given numbers are 651, 438, 684, 387

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

Apply this formula for all numbers.

Step1:

LCM(651, 438) = 95046

GCD(651, 438) = ( 651 x 438 ) / 95046

= 651 / 438

= 651

Step2:

LCM(3, 684) = 684

GCD(3, 684) = ( 3 x 684 ) / 684

= 3 / 684

= 3

Step3:

LCM(3, 387) = 387

GCD(3, 387) = ( 3 x 387 ) / 387

= 3 / 387

= 3

So, Greatest Common Divisor of 651, 438, 684, 387 is 3
