Given numbers are 987, 387, 543, 970

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

Apply this formula for all numbers.

Step1:

LCM(987, 387) = 127323

GCD(987, 387) = ( 987 x 387 ) / 127323

= 987 / 387

= 987

Step2:

LCM(3, 543) = 543

GCD(3, 543) = ( 3 x 543 ) / 543

= 3 / 543

= 3

Step3:

LCM(3, 970) = 2910

GCD(3, 970) = ( 3 x 970 ) / 2910

= 3 / 970

= 3

So, Greatest Common Divisor of 987, 387, 543, 970 is 1
