Given numbers are 654, 921, 260, 387

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

Apply this formula for all numbers.

Step1:

LCM(654, 921) = 200778

GCD(654, 921) = ( 654 x 921 ) / 200778

= 654 / 921

= 654

Step2:

LCM(3, 260) = 780

GCD(3, 260) = ( 3 x 260 ) / 780

= 3 / 260

= 3

Step3:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

So, Greatest Common Divisor of 654, 921, 260, 387 is 1
