Given numbers are 684, 284, 921, 964

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

Apply this formula for all numbers.

Step1:

LCM(684, 284) = 48564

GCD(684, 284) = ( 684 x 284 ) / 48564

= 684 / 284

= 684

Step2:

LCM(4, 921) = 3684

GCD(4, 921) = ( 4 x 921 ) / 3684

= 4 / 921

= 4

Step3:

LCM(1, 964) = 964

GCD(1, 964) = ( 1 x 964 ) / 964

= 1 / 964

= 1

So, Greatest Common Divisor of 684, 284, 921, 964 is 1
