Given numbers are 987, 225, 98, 786

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

Apply this formula for all numbers.

Step1:

LCM(987, 225) = 74025

GCD(987, 225) = ( 987 x 225 ) / 74025

= 987 / 225

= 987

Step2:

LCM(3, 98) = 294

GCD(3, 98) = ( 3 x 98 ) / 294

= 3 / 98

= 3

Step3:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 987, 225, 98, 786 is 1
