Given numbers are 136, 778, 639, 379

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

Apply this formula for all numbers.

Step1:

LCM(136, 778) = 52904

GCD(136, 778) = ( 136 x 778 ) / 52904

= 136 / 778

= 136

Step2:

LCM(2, 639) = 1278

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

= 2 / 639

= 2

Step3:

LCM(1, 379) = 379

GCD(1, 379) = ( 1 x 379 ) / 379

= 1 / 379

= 1

So, Greatest Common Divisor of 136, 778, 639, 379 is 1
