Given numbers are 630, 822, 972, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 822) = 86310
GCD(630, 822) = ( 630 x 822 ) / 86310
= 630 / 822
= 630
Step2:
LCM(6, 972) = 972
GCD(6, 972) = ( 6 x 972 ) / 972
= 6 / 972
= 6
Step3:
LCM(6, 785) = 4710
GCD(6, 785) = ( 6 x 785 ) / 4710
= 6 / 785
= 6
So, Greatest Common Divisor of 630, 822, 972, 785 is 1
