Given numbers are 847, 691, 347, 210
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(847, 691) = 585277
GCD(847, 691) = ( 847 x 691 ) / 585277
= 847 / 691
= 847
Step2:
LCM(1, 347) = 347
GCD(1, 347) = ( 1 x 347 ) / 347
= 1 / 347
= 1
Step3:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
So, Greatest Common Divisor of 847, 691, 347, 210 is 1
