Given numbers are 220, 206, 542, 217
The list of prime factors of all numbers are
Prime factors of 220 are 2 x 2 x 5 x 11
Prime factors of 206 are 2 x 103
Prime factors of 542 are 2 x 271
Prime factors of 217 are 7 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 220, 206, 542, 217
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 206) = 22660
GCD(220, 206) = ( 220 x 206 ) / 22660
= 220 / 206
= 220
Step2:
LCM(2, 542) = 542
GCD(2, 542) = ( 2 x 542 ) / 542
= 2 / 542
= 2
Step3:
LCM(2, 217) = 434
GCD(2, 217) = ( 2 x 217 ) / 434
= 2 / 217
= 2
So, Greatest Common Divisor of 220, 206, 542, 217 is 1
