Given numbers are 623, 659, 213, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(623, 659) = 410557
GCD(623, 659) = ( 623 x 659 ) / 410557
= 623 / 659
= 623
Step2:
LCM(1, 213) = 213
GCD(1, 213) = ( 1 x 213 ) / 213
= 1 / 213
= 1
Step3:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
So, Greatest Common Divisor of 623, 659, 213, 813 is 1
