Given numbers are 790, 987, 427, 387

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

Apply this formula for all numbers.

Step1:

LCM(790, 987) = 779730

GCD(790, 987) = ( 790 x 987 ) / 779730

= 790 / 987

= 790

Step2:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

Step3:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

So, Greatest Common Divisor of 790, 987, 427, 387 is 1
