Prime factors of 445 are 5 x 89
Prime factors of 922 are 2 x 461
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 361, 780, 445, 922
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(361, 780) = 281580
GCD(361, 780) = ( 361 x 780 ) / 281580
= 361 / 780
= 361
Step2:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
Step3:
LCM(1, 922) = 922
GCD(1, 922) = ( 1 x 922 ) / 922
= 1 / 922
= 1
So, Greatest Common Divisor of 361, 780, 445, 922 is 1
