Given numbers are 302, 990, 675, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(302, 990) = 149490
GCD(302, 990) = ( 302 x 990 ) / 149490
= 302 / 990
= 302
Step2:
LCM(2, 675) = 1350
GCD(2, 675) = ( 2 x 675 ) / 1350
= 2 / 675
= 2
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 302, 990, 675, 490 is 1
