Given numbers are 630, 882, 321, 860
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 882) = 4410
GCD(630, 882) = ( 630 x 882 ) / 4410
= 630 / 882
= 630
Step2:
LCM(126, 321) = 13482
GCD(126, 321) = ( 126 x 321 ) / 13482
= 126 / 321
= 126
Step3:
LCM(3, 860) = 2580
GCD(3, 860) = ( 3 x 860 ) / 2580
= 3 / 860
= 3
So, Greatest Common Divisor of 630, 882, 321, 860 is 1
