Given numbers are 647, 190, 708, 419

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

Apply this formula for all numbers.

Step1:

LCM(647, 190) = 122930

GCD(647, 190) = ( 647 x 190 ) / 122930

= 647 / 190

= 647

Step2:

LCM(1, 708) = 708

GCD(1, 708) = ( 1 x 708 ) / 708

= 1 / 708

= 1

Step3:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

So, Greatest Common Divisor of 647, 190, 708, 419 is 1
