Given numbers are 378, 427, 679, 655

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

Apply this formula for all numbers.

Step1:

LCM(378, 427) = 23058

GCD(378, 427) = ( 378 x 427 ) / 23058

= 378 / 427

= 378

Step2:

LCM(7, 679) = 679

GCD(7, 679) = ( 7 x 679 ) / 679

= 7 / 679

= 7

Step3:

LCM(7, 655) = 4585

GCD(7, 655) = ( 7 x 655 ) / 4585

= 7 / 655

= 7

So, Greatest Common Divisor of 378, 427, 679, 655 is 1
