Given numbers are 998, 822, 579, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(998, 822) = 410178
GCD(998, 822) = ( 998 x 822 ) / 410178
= 998 / 822
= 998
Step2:
LCM(2, 579) = 1158
GCD(2, 579) = ( 2 x 579 ) / 1158
= 2 / 579
= 2
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 998, 822, 579, 781 is 1
