Given numbers are 431, 840, 853, 847
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(431, 840) = 362040
GCD(431, 840) = ( 431 x 840 ) / 362040
= 431 / 840
= 431
Step2:
LCM(1, 853) = 853
GCD(1, 853) = ( 1 x 853 ) / 853
= 1 / 853
= 1
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 431, 840, 853, 847 is 1
