Given numbers are 839, 705, 410, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(839, 705) = 591495
GCD(839, 705) = ( 839 x 705 ) / 591495
= 839 / 705
= 839
Step2:
LCM(1, 410) = 410
GCD(1, 410) = ( 1 x 410 ) / 410
= 1 / 410
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 839, 705, 410, 644 is 1
