Given numbers are 814, 210, 889, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(814, 210) = 85470
GCD(814, 210) = ( 814 x 210 ) / 85470
= 814 / 210
= 814
Step2:
LCM(2, 889) = 1778
GCD(2, 889) = ( 2 x 889 ) / 1778
= 2 / 889
= 2
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 814, 210, 889, 438 is 1
