Given numbers are 782, 291, 57, 842

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

Apply this formula for all numbers.

Step1:

LCM(782, 291) = 227562

GCD(782, 291) = ( 782 x 291 ) / 227562

= 782 / 291

= 782

Step2:

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

= 1 / 57

= 1

Step3:

LCM(1, 842) = 842

GCD(1, 842) = ( 1 x 842 ) / 842

= 1 / 842

= 1

So, Greatest Common Divisor of 782, 291, 57, 842 is 1
