Given numbers are 707,385,478,578,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 707,385,478,578,803 is 392130571910.
Find LCM of 707,385,478,578,803 with Prime Factorization
2 | 707, 385, 478, 578, 803 |
7 | 707, 385, 239, 289, 803 |
11 | 101, 55, 239, 289, 803 |
101, 5, 239, 289, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 101 x 5 x 239 x 289 x 73 = 392130571910
Therefore, the lowest common multiple of 707,385,478,578,803 is 392130571910.
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.
707 x 385 x 478 x 578 x 803 = 60388108074140
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.
707 : 1, 7, 101, 707
385 : 1, 5, 7, 11, 35, 55, 77, 385
478 : 1, 2, 239, 478
578 : 1, 2, 17, 34, 289, 578
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,385,478,578,803, is 1.
Now, the common factors can be found like this.
707:7x 101
385:5x 7x 11
478:2x 239
578:2x 17x 17
803:11x 73
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 11 = 154
Therefore, the value for common factors is 154.
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 = 60388108074140/(1x154)
LCM = 60388108074140/154
LCM = 392130571910
Thus, we can understand that the LCM of 707,385,478,578,803 is 392130571910.
