Given numbers are 654, 987, 157, 413

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

Apply this formula for all numbers.

Step1:

LCM(654, 987) = 215166

GCD(654, 987) = ( 654 x 987 ) / 215166

= 654 / 987

= 654

Step2:

LCM(3, 157) = 471

GCD(3, 157) = ( 3 x 157 ) / 471

= 3 / 157

= 3

Step3:

LCM(1, 413) = 413

GCD(1, 413) = ( 1 x 413 ) / 413

= 1 / 413

= 1

So, Greatest Common Divisor of 654, 987, 157, 413 is 1
