Given numbers are 671, 347, 857, 165
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(671, 347) = 232837
GCD(671, 347) = ( 671 x 347 ) / 232837
= 671 / 347
= 671
Step2:
LCM(1, 857) = 857
GCD(1, 857) = ( 1 x 857 ) / 857
= 1 / 857
= 1
Step3:
LCM(1, 165) = 165
GCD(1, 165) = ( 1 x 165 ) / 165
= 1 / 165
= 1
So, Greatest Common Divisor of 671, 347, 857, 165 is 1
