Given numbers are 425, 721, 987, 740

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

Apply this formula for all numbers.

Step1:

LCM(425, 721) = 306425

GCD(425, 721) = ( 425 x 721 ) / 306425

= 425 / 721

= 425

Step2:

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

= 1 / 987

= 1

Step3:

LCM(1, 740) = 740

GCD(1, 740) = ( 1 x 740 ) / 740

= 1 / 740

= 1

So, Greatest Common Divisor of 425, 721, 987, 740 is 1
