Given numbers are 515, 715, 808, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(515, 715) = 73645
GCD(515, 715) = ( 515 x 715 ) / 73645
= 515 / 715
= 515
Step2:
LCM(5, 808) = 4040
GCD(5, 808) = ( 5 x 808 ) / 4040
= 5 / 808
= 5
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 515, 715, 808, 490 is 1
