Given numbers are 749,390,179,506
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,390,179,506 is 13228785570.
Find LCM of 749,390,179,506 with Prime Factorization
| 2 | 749, 390, 179, 506 |
| 749, 195, 179, 253 |
Multiply the prime numbers at the bottom and the left side.
2 x 749 x 195 x 179 x 253 = 13228785570
Therefore, the lowest common multiple of 749,390,179,506 is 13228785570.
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 390 x 179 x 506 = 26457571140
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
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
179 : 1, 179
506 : 1, 2, 11, 22, 23, 46, 253, 506
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,390,179,506, is 1.
Now, the common factors can be found like this.
749:7x 107
390:2x 3x 5x 13
179:179
506:2x 11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 26457571140/(1x2)
LCM = 26457571140/2
LCM = 13228785570
Thus, we can understand that the LCM of 749,390,179,506 is 13228785570.
