Given numbers are 668, 520, 377, 813

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

Apply this formula for all numbers.

Step1:

LCM(668, 520) = 86840

GCD(668, 520) = ( 668 x 520 ) / 86840

= 668 / 520

= 668

Step2:

LCM(4, 377) = 1508

GCD(4, 377) = ( 4 x 377 ) / 1508

= 4 / 377

= 4

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 668, 520, 377, 813 is 1
