Given numbers are 220, 222, 538, 245
The list of prime factors of all numbers are
Prime factors of 220 are 2 x 2 x 5 x 11
Prime factors of 222 are 2 x 3 x 37
Prime factors of 538 are 2 x 269
Prime factors of 245 are 5 x 7 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 220, 222, 538, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 222) = 24420
GCD(220, 222) = ( 220 x 222 ) / 24420
= 220 / 222
= 220
Step2:
LCM(2, 538) = 538
GCD(2, 538) = ( 2 x 538 ) / 538
= 2 / 538
= 2
Step3:
LCM(2, 245) = 490
GCD(2, 245) = ( 2 x 245 ) / 490
= 2 / 245
= 2
So, Greatest Common Divisor of 220, 222, 538, 245 is 1
