Given numbers are 699, 438, 718, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(699, 438) = 102054
GCD(699, 438) = ( 699 x 438 ) / 102054
= 699 / 438
= 699
Step2:
LCM(3, 718) = 2154
GCD(3, 718) = ( 3 x 718 ) / 2154
= 3 / 718
= 3
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 699, 438, 718, 921 is 1
