Given numbers are 875, 190, 171, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(875, 190) = 33250
GCD(875, 190) = ( 875 x 190 ) / 33250
= 875 / 190
= 875
Step2:
LCM(5, 171) = 855
GCD(5, 171) = ( 5 x 171 ) / 855
= 5 / 171
= 5
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 875, 190, 171, 809 is 1
