Given numbers are 378, 581, 289, 777

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

Apply this formula for all numbers.

Step1:

LCM(378, 581) = 31374

GCD(378, 581) = ( 378 x 581 ) / 31374

= 378 / 581

= 378

Step2:

LCM(7, 289) = 2023

GCD(7, 289) = ( 7 x 289 ) / 2023

= 7 / 289

= 7

Step3:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

So, Greatest Common Divisor of 378, 581, 289, 777 is 1
