Given numbers are 240, 156, 443, 342
The list of prime factors of all numbers are
Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5
Prime factors of 156 are 2 x 2 x 3 x 13
Prime factors of 443 are 443
Prime factors of 342 are 2 x 3 x 3 x 19
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 240, 156, 443, 342
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(240, 156) = 3120
GCD(240, 156) = ( 240 x 156 ) / 3120
= 240 / 156
= 240
Step2:
LCM(12, 443) = 5316
GCD(12, 443) = ( 12 x 443 ) / 5316
= 12 / 443
= 12
Step3:
LCM(1, 342) = 342
GCD(1, 342) = ( 1 x 342 ) / 342
= 1 / 342
= 1
So, Greatest Common Divisor of 240, 156, 443, 342 is 1
