Given numbers are 378, 920, 719, 639

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

Apply this formula for all numbers.

Step1:

LCM(378, 920) = 173880

GCD(378, 920) = ( 378 x 920 ) / 173880

= 378 / 920

= 378

Step2:

LCM(2, 719) = 1438

GCD(2, 719) = ( 2 x 719 ) / 1438

= 2 / 719

= 2

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 378, 920, 719, 639 is 1
