Given numbers are 378, 283, 665, 123

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

Apply this formula for all numbers.

Step1:

LCM(378, 283) = 106974

GCD(378, 283) = ( 378 x 283 ) / 106974

= 378 / 283

= 378

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 378, 283, 665, 123 is 1
