Given numbers are 987, 958, 23, 647

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

Apply this formula for all numbers.

Step1:

LCM(987, 958) = 945546

GCD(987, 958) = ( 987 x 958 ) / 945546

= 987 / 958

= 987

Step2:

LCM(1, 23) = 23

GCD(1, 23) = ( 1 x 23 ) / 23

= 1 / 23

= 1

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 987, 958, 23, 647 is 1
