Given numbers are 989, 129, 907, 509

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

Apply this formula for all numbers.

Step1:

LCM(989, 129) = 2967

GCD(989, 129) = ( 989 x 129 ) / 2967

= 989 / 129

= 989

Step2:

LCM(43, 907) = 39001

GCD(43, 907) = ( 43 x 907 ) / 39001

= 43 / 907

= 43

Step3:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

So, Greatest Common Divisor of 989, 129, 907, 509 is 1
