Given numbers are 658, 399, 813, 664

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

Apply this formula for all numbers.

Step1:

LCM(658, 399) = 37506

GCD(658, 399) = ( 658 x 399 ) / 37506

= 658 / 399

= 658

Step2:

LCM(7, 813) = 5691

GCD(7, 813) = ( 7 x 813 ) / 5691

= 7 / 813

= 7

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 658, 399, 813, 664 is 1
