Given numbers are 222, 670, 810, 791
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(222, 670) = 74370
GCD(222, 670) = ( 222 x 670 ) / 74370
= 222 / 670
= 222
Step2:
LCM(2, 810) = 810
GCD(2, 810) = ( 2 x 810 ) / 810
= 2 / 810
= 2
Step3:
LCM(2, 791) = 1582
GCD(2, 791) = ( 2 x 791 ) / 1582
= 2 / 791
= 2
So, Greatest Common Divisor of 222, 670, 810, 791 is 1
