Given numbers are 705, 630, 384, 963
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 630) = 29610
GCD(705, 630) = ( 705 x 630 ) / 29610
= 705 / 630
= 705
Step2:
LCM(15, 384) = 1920
GCD(15, 384) = ( 15 x 384 ) / 1920
= 15 / 384
= 15
Step3:
LCM(3, 963) = 963
GCD(3, 963) = ( 3 x 963 ) / 963
= 3 / 963
= 3
So, Greatest Common Divisor of 705, 630, 384, 963 is 3
