GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(320, 278) = 44480
GCD(320, 278) = ( 320 x 278 ) / 44480
= 320 / 278
= 320
Step2:
LCM(2, 28) = 28
GCD(2, 28) = ( 2 x 28 ) / 28
= 2 / 28
= 2
Step3:
LCM(2, 630) = 630
GCD(2, 630) = ( 2 x 630 ) / 630
= 2 / 630
= 2
So, Greatest Common Divisor of 320, 278, 28, 630 is 2
