Given numbers are 630,550,643,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 630,550,643,400 is 178239600.
Find LCM of 630,550,643,400 with Prime Factorization
| 2 | 630, 550, 643, 400 |
| 5 | 315, 275, 643, 200 |
| 5 | 63, 55, 643, 40 |
| 63, 11, 643, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 63 x 11 x 643 x 8 = 178239600
Therefore, the lowest common multiple of 630,550,643,400 is 178239600.
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.
630 x 550 x 643 x 400 = 89119800000
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
643 : 1, 643
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,550,643,400, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
550:2x 5x 5x 11
643:643
400:2x 2x 2x 2x 5x 5
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 5x 5x 5 = 500
Therefore, the value for common factors is 500.
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 = 89119800000/(1x500)
LCM = 89119800000/500
LCM = 178239600
Thus, we can understand that the LCM of 630,550,643,400 is 178239600.
