Given numbers are 749,623,798,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,623,798,974 is 3700885398.
Find LCM of 749,623,798,974 with Prime Factorization
| 2 | 749, 623, 798, 974 |
| 7 | 749, 623, 399, 487 |
| 107, 89, 57, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 107 x 89 x 57 x 487 = 3700885398
Therefore, the lowest common multiple of 749,623,798,974 is 3700885398.
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.
749 x 623 x 798 x 974 = 362686769004
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.
749 : 1, 7, 107, 749
623 : 1, 7, 89, 623
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,623,798,974, is 1.
Now, the common factors can be found like this.
749:7x 107
623:7x 89
798:2x 3x 7x 19
974:2x 487
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 7 = 98
Therefore, the value for common factors is 98.
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 = 362686769004/(1x98)
LCM = 362686769004/98
LCM = 3700885398
Thus, we can understand that the LCM of 749,623,798,974 is 3700885398.
