Given numbers are 646, 782, 787, 873

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

Apply this formula for all numbers.

Step1:

LCM(646, 782) = 14858

GCD(646, 782) = ( 646 x 782 ) / 14858

= 646 / 782

= 646

Step2:

LCM(34, 787) = 26758

GCD(34, 787) = ( 34 x 787 ) / 26758

= 34 / 787

= 34

Step3:

LCM(1, 873) = 873

GCD(1, 873) = ( 1 x 873 ) / 873

= 1 / 873

= 1

So, Greatest Common Divisor of 646, 782, 787, 873 is 1
