Given numbers are 654, 387, 214, 641

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

Apply this formula for all numbers.

Step1:

LCM(654, 387) = 84366

GCD(654, 387) = ( 654 x 387 ) / 84366

= 654 / 387

= 654

Step2:

LCM(3, 214) = 642

GCD(3, 214) = ( 3 x 214 ) / 642

= 3 / 214

= 3

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 654, 387, 214, 641 is 1
