Given numbers are 782, 742, 639, 894

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

Apply this formula for all numbers.

Step1:

LCM(782, 742) = 290122

GCD(782, 742) = ( 782 x 742 ) / 290122

= 782 / 742

= 782

Step2:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

Step3:

LCM(1, 894) = 894

GCD(1, 894) = ( 1 x 894 ) / 894

= 1 / 894

= 1

So, Greatest Common Divisor of 782, 742, 639, 894 is 1
