Given numbers are 705, 880, 645, 443
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 880) = 124080
GCD(705, 880) = ( 705 x 880 ) / 124080
= 705 / 880
= 705
Step2:
LCM(5, 645) = 645
GCD(5, 645) = ( 5 x 645 ) / 645
= 5 / 645
= 5
Step3:
LCM(5, 443) = 2215
GCD(5, 443) = ( 5 x 443 ) / 2215
= 5 / 443
= 5
So, Greatest Common Divisor of 705, 880, 645, 443 is 1
