Given numbers are 4004,9620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 4004,9620 is 740740.
Find LCM of 4004,9620 with Prime Factorization
| 2 | 4004, 9620 |
| 2 | 2002, 4810 |
| 13 | 1001, 2405 |
| 77, 185 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 77 x 185 = 740740
Therefore, the lowest common multiple of 4004,9620 is 740740.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
4004 x 9620 = 38518480
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
4004 : 1, 2, 4, 7, 11, 13, 14, 22, 26, 28, 44, 52, 77, 91, 143, 154, 182, 286, 308, 364, 572, 1001, 2002, 4004
9620 : 1, 2, 4, 5, 10, 13, 20, 26, 37, 52, 65, 74, 130, 148, 185, 260, 370, 481, 740, 962, 1924, 2405, 4810, 9620
52 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 4004,9620, is 52.
Now, the common factors can be found like this.
4004:2x 2x 7x 11x 13
9620:2x 2x 5x 13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 38518480/(52x1)
LCM = 38518480/52
LCM = 740740
Thus, we can understand that the LCM of 4004,9620 is 740740.
