The list of prime factors of all numbers are
Prime factors of 414 are 2 x 3 x 3 x 23
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 553 are 7 x 79
Prime factors of 121 are 11 x 11
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 414, 660, 553, 121
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(414, 660) = 45540
GCD(414, 660) = ( 414 x 660 ) / 45540
= 414 / 660
= 414
Step2:
LCM(6, 553) = 3318
GCD(6, 553) = ( 6 x 553 ) / 3318
= 6 / 553
= 6
Step3:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
So, Greatest Common Divisor of 414, 660, 553, 121 is 1
