Given numbers are 988, 245, 209, 202
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(988, 245) = 242060
GCD(988, 245) = ( 988 x 245 ) / 242060
= 988 / 245
= 988
Step2:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
Step3:
LCM(1, 202) = 202
GCD(1, 202) = ( 1 x 202 ) / 202
= 1 / 202
= 1
So, Greatest Common Divisor of 988, 245, 209, 202 is 1
