Given numbers are 124, 342, 671, 989

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

Apply this formula for all numbers.

Step1:

LCM(124, 342) = 21204

GCD(124, 342) = ( 124 x 342 ) / 21204

= 124 / 342

= 124

Step2:

LCM(2, 671) = 1342

GCD(2, 671) = ( 2 x 671 ) / 1342

= 2 / 671

= 2

Step3:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

So, Greatest Common Divisor of 124, 342, 671, 989 is 1
