Given numbers are 989, 786, 720, 762

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

Apply this formula for all numbers.

Step1:

LCM(989, 786) = 777354

GCD(989, 786) = ( 989 x 786 ) / 777354

= 989 / 786

= 989

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 762) = 762

GCD(1, 762) = ( 1 x 762 ) / 762

= 1 / 762

= 1

So, Greatest Common Divisor of 989, 786, 720, 762 is 1
