Given numbers are 358,107,550,690,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 358,107,550,690,642 is 726856350.
Find LCM of 358,107,550,690,642 with Prime Factorization
| 2 | 358, 107, 550, 690, 642 |
| 3 | 179, 107, 275, 345, 321 |
| 5 | 179, 107, 275, 115, 107 |
| 107 | 179, 107, 55, 23, 107 |
| 179, 1, 55, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 107 x 179 x 1 x 55 x 23 x 1 = 726856350
Therefore, the lowest common multiple of 358,107,550,690,642 is 726856350.
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.
358 x 107 x 550 x 690 x 642 = 9332835534000
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.
358 : 1, 2, 179, 358
107 : 1, 107
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 358,107,550,690,642, is 1.
Now, the common factors can be found like this.
358:2x 179
107:107
550:2x 5x 5x 11
690:2x 3x 5x 23
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 5x 107 = 12840
Therefore, the value for common factors is 12840.
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 = 9332835534000/(1x12840)
LCM = 9332835534000/12840
LCM = 726856350
Thus, we can understand that the LCM of 358,107,550,690,642 is 726856350.
