Given numbers are 545, 215, 618, 221
The list of prime factors of all numbers are
Prime factors of 545 are 5 x 109
Prime factors of 215 are 5 x 43
Prime factors of 618 are 2 x 3 x 103
Prime factors of 221 are 13 x 17
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 545, 215, 618, 221
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(545, 215) = 23435
GCD(545, 215) = ( 545 x 215 ) / 23435
= 545 / 215
= 545
Step2:
LCM(5, 618) = 3090
GCD(5, 618) = ( 5 x 618 ) / 3090
= 5 / 618
= 5
Step3:
LCM(1, 221) = 221
GCD(1, 221) = ( 1 x 221 ) / 221
= 1 / 221
= 1
So, Greatest Common Divisor of 545, 215, 618, 221 is 1
