Given numbers are 630, 830, 462, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 830) = 52290
GCD(630, 830) = ( 630 x 830 ) / 52290
= 630 / 830
= 630
Step2:
LCM(10, 462) = 2310
GCD(10, 462) = ( 10 x 462 ) / 2310
= 10 / 462
= 10
Step3:
LCM(2, 678) = 678
GCD(2, 678) = ( 2 x 678 ) / 678
= 2 / 678
= 2
So, Greatest Common Divisor of 630, 830, 462, 678 is 2
