GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(392, 140) = 1960
GCD(392, 140) = ( 392 x 140 ) / 1960
= 392 / 140
= 392
Step2:
LCM(28, 284) = 1988
GCD(28, 284) = ( 28 x 284 ) / 1988
= 28 / 284
= 28
Step3:
LCM(4, 490) = 980
GCD(4, 490) = ( 4 x 490 ) / 980
= 4 / 490
= 4
So, Greatest Common Divisor of 392, 140, 284, 490 is 2
