Given numbers are 847, 840, 676, 170
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(847, 840) = 101640
GCD(847, 840) = ( 847 x 840 ) / 101640
= 847 / 840
= 847
Step2:
LCM(7, 676) = 4732
GCD(7, 676) = ( 7 x 676 ) / 4732
= 7 / 676
= 7
Step3:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
So, Greatest Common Divisor of 847, 840, 676, 170 is 1
