Given numbers are 450, 219, 278, 978

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

Apply this formula for all numbers.

Step1:

LCM(450, 219) = 32850

GCD(450, 219) = ( 450 x 219 ) / 32850

= 450 / 219

= 450

Step2:

LCM(3, 278) = 834

GCD(3, 278) = ( 3 x 278 ) / 834

= 3 / 278

= 3

Step3:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 450, 219, 278, 978 is 1
