Given numbers are 870, 585, 476, 343
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 585) = 33930
GCD(870, 585) = ( 870 x 585 ) / 33930
= 870 / 585
= 870
Step2:
LCM(15, 476) = 7140
GCD(15, 476) = ( 15 x 476 ) / 7140
= 15 / 476
= 15
Step3:
LCM(1, 343) = 343
GCD(1, 343) = ( 1 x 343 ) / 343
= 1 / 343
= 1
So, Greatest Common Divisor of 870, 585, 476, 343 is 1
