Given numbers are 284, 632, 987, 840

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

Apply this formula for all numbers.

Step1:

LCM(284, 632) = 44872

GCD(284, 632) = ( 284 x 632 ) / 44872

= 284 / 632

= 284

Step2:

LCM(4, 987) = 3948

GCD(4, 987) = ( 4 x 987 ) / 3948

= 4 / 987

= 4

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 284, 632, 987, 840 is 1
