Given numbers are 160, 143, 236, 644
The list of prime factors of all numbers are
Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5
Prime factors of 143 are 11 x 13
Prime factors of 236 are 2 x 2 x 59
Prime factors of 644 are 2 x 2 x 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 160, 143, 236, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(160, 143) = 22880
GCD(160, 143) = ( 160 x 143 ) / 22880
= 160 / 143
= 160
Step2:
LCM(1, 236) = 236
GCD(1, 236) = ( 1 x 236 ) / 236
= 1 / 236
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 160, 143, 236, 644 is 1
