Given numbers are 784, 623, 490, 499
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 623) = 69776
GCD(784, 623) = ( 784 x 623 ) / 69776
= 784 / 623
= 784
Step2:
LCM(7, 490) = 490
GCD(7, 490) = ( 7 x 490 ) / 490
= 7 / 490
= 7
Step3:
LCM(7, 499) = 3493
GCD(7, 499) = ( 7 x 499 ) / 3493
= 7 / 499
= 7
So, Greatest Common Divisor of 784, 623, 490, 499 is 1
