Given numbers are 209, 253, 551, 890
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(209, 253) = 4807
GCD(209, 253) = ( 209 x 253 ) / 4807
= 209 / 253
= 209
Step2:
LCM(11, 551) = 6061
GCD(11, 551) = ( 11 x 551 ) / 6061
= 11 / 551
= 11
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 209, 253, 551, 890 is 1
