Given numbers are 390, 786, 280, 419

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

Apply this formula for all numbers.

Step1:

LCM(390, 786) = 51090

GCD(390, 786) = ( 390 x 786 ) / 51090

= 390 / 786

= 390

Step2:

LCM(6, 280) = 840

GCD(6, 280) = ( 6 x 280 ) / 840

= 6 / 280

= 6

Step3:

LCM(2, 419) = 838

GCD(2, 419) = ( 2 x 419 ) / 838

= 2 / 419

= 2

So, Greatest Common Divisor of 390, 786, 280, 419 is 1
