Given numbers are 989, 387, 635

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

Apply this formula for all numbers.

Step1:

LCM(989, 387) = 8901

GCD(989, 387) = ( 989 x 387 ) / 8901

= 989 / 387

= 989

Step2:

LCM(43, 635) = 27305

GCD(43, 635) = ( 43 x 635 ) / 27305

= 43 / 635

= 43

So, Greatest Common Divisor of 989, 387, 635 is 1
