Given numbers are 217, 308, 226, 210
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 308) = 9548
GCD(217, 308) = ( 217 x 308 ) / 9548
= 217 / 308
= 217
Step2:
LCM(7, 226) = 1582
GCD(7, 226) = ( 7 x 226 ) / 1582
= 7 / 226
= 7
Step3:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
So, Greatest Common Divisor of 217, 308, 226, 210 is 1
