Given numbers are 660, 121, 77, 358
The list of prime factors of all numbers are
Prime factors of 660 are 2 x 2 x 3 x 5 x 11
Prime factors of 121 are 11 x 11
Prime factors of 77 are 7 x 11
Prime factors of 358 are 2 x 179
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 660, 121, 77, 358
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 121) = 7260
GCD(660, 121) = ( 660 x 121 ) / 7260
= 660 / 121
= 660
Step2:
LCM(11, 77) = 77
GCD(11, 77) = ( 11 x 77 ) / 77
= 11 / 77
= 11
Step3:
LCM(11, 358) = 3938
GCD(11, 358) = ( 11 x 358 ) / 3938
= 11 / 358
= 11
So, Greatest Common Divisor of 660, 121, 77, 358 is 1
