Given numbers are 836, 653, 639, 778

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

Apply this formula for all numbers.

Step1:

LCM(836, 653) = 545908

GCD(836, 653) = ( 836 x 653 ) / 545908

= 836 / 653

= 836

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 836, 653, 639, 778 is 1
