Given numbers are 310, 705, 223, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(310, 705) = 43710
GCD(310, 705) = ( 310 x 705 ) / 43710
= 310 / 705
= 310
Step2:
LCM(5, 223) = 1115
GCD(5, 223) = ( 5 x 223 ) / 1115
= 5 / 223
= 5
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 310, 705, 223, 644 is 1
