The only factor common to 7 and 4 is 1 because 7 is prime.
The least common multiple is the least factor that can be common in every number. In algebra , L.C.M of 19, 7 and 4 is 19 *7* 4 =532. 532 is the least common multiple of 19 7 and 4.
The Least Common Multiple (LCM) of 4 and 7 is 28.The Least Common Multiple (LCM) for 4 7 is 28.
The factors of 14 are 1, 2, 7, and 14. The factors of 28 are 1, 2, 4, 7, 14, and 28. The common factors of 14 and 28 are 1, 2, 7, and 14. Therefore, the least (smallest) common factor is 1.
The LCF of 4 & 7 is... 1 ! There are no other common factors.
Answer: 1 The factors of 28 are 1, 2, 4, 7, 14, and 28. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors are 1, 2, and 4; the least (smallest) common factor is 1.
The Least Common Multiple of 4 and 7 is 28.
The factors of 4 are 1, 2, and 4. The factors of 7 are 1 and 7. The only common factor is 1.
4/7 and 3/5 have an LCD of 35 since they 7 and 5 have no common factors.
The least common multiple of 4 , 7 , 12 = 84
The least common multiple of 4, 7, and 9 is 252.
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.
The factors of 56 are 1, 2, 4, 7, 8, 14, 28, 56. For them to be common, they need to be compared to another set of factors.
