Given numbers are 721,348,280,133,700
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,348,280,133,700 is 238362600.
Find LCM of 721,348,280,133,700 with Prime Factorization
| 2 | 721, 348, 280, 133, 700 |
| 2 | 721, 174, 140, 133, 350 |
| 5 | 721, 87, 70, 133, 175 |
| 7 | 721, 87, 14, 133, 35 |
| 103, 87, 2, 19, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 103 x 87 x 2 x 19 x 5 = 238362600
Therefore, the lowest common multiple of 721,348,280,133,700 is 238362600.
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.
721 x 348 x 280 x 133 x 700 = 6540669744000
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.
721 : 1, 7, 103, 721
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
133 : 1, 7, 19, 133
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,348,280,133,700, is 1.
Now, the common factors can be found like this.
721:7x 103
348:2x 2x 3x 29
280:2x 2x 2x 5x 7
133:7x 19
700:2x 2x 5x 5x 7
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 2x 5x 7x 7x 7 = 27440
Therefore, the value for common factors is 27440.
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 = 6540669744000/(1x27440)
LCM = 6540669744000/27440
LCM = 238362600
Thus, we can understand that the LCM of 721,348,280,133,700 is 238362600.
