Given numbers are 730, 817, 490, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(730, 817) = 596410
GCD(730, 817) = ( 730 x 817 ) / 596410
= 730 / 817
= 730
Step2:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 730, 817, 490, 663 is 1
