Given numbers are 438, 207, 302, 321
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 207) = 30222
GCD(438, 207) = ( 438 x 207 ) / 30222
= 438 / 207
= 438
Step2:
LCM(3, 302) = 906
GCD(3, 302) = ( 3 x 302 ) / 906
= 3 / 302
= 3
Step3:
LCM(1, 321) = 321
GCD(1, 321) = ( 1 x 321 ) / 321
= 1 / 321
= 1
So, Greatest Common Divisor of 438, 207, 302, 321 is 1
