Given numbers are 778, 980, 89, 620

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

Apply this formula for all numbers.

Step1:

LCM(778, 980) = 381220

GCD(778, 980) = ( 778 x 980 ) / 381220

= 778 / 980

= 778

Step2:

LCM(2, 89) = 178

GCD(2, 89) = ( 2 x 89 ) / 178

= 2 / 89

= 2

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 778, 980, 89, 620 is 1
