945 is the lowest common denominator. 3 is the greatest common factor.
To find the highest common factor (HCF) of 735 and 945, we first need to factorize both numbers. The prime factors of 735 are 3 x 5 x 7 x 7, and the prime factors of 945 are 3 x 3 x 3 x 5 x 7. To find the HCF, we identify the common prime factors and multiply them together: 3 x 5 x 7 = 105. Therefore, the highest common factor of 735 and 945 is 105.
No they are not.Two numbers are relatively prime if their greatest common factor is 1.For example, 8 and 15 are relatively prime.
945 has several factors. The factors of 945 are: 1 3 5 7 9 15 21 27 35 45 63 105 135 189 315 and 945.
The Least Common Multiple (LCM) of 7, 27, and 45 is 945. 7 is prime and 27 = 33; they have no common factors so their LCM is 7x27=189. Now bring in 45 = 32x5. The only new factor here is 5, so the LCM of the 3 numbers is 189x5 = 945.
