Given numbers are 707,817,105,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 707,817,105,644 is 797114220.
Find LCM of 707,817,105,644 with Prime Factorization
| 7 | 707, 817, 105, 644 |
| 101, 817, 15, 92 |
Multiply the prime numbers at the bottom and the left side.
7 x 101 x 817 x 15 x 92 = 797114220
Therefore, the lowest common multiple of 707,817,105,644 is 797114220.
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 817 x 105 x 644 = 39058596780
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
817 : 1, 19, 43, 817
105 : 1, 3, 5, 7, 15, 21, 35, 105
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,817,105,644, is 1.
Now, the common factors can be found like this.
707:7x 101
817:19x 43
105:3x 5x 7
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 39058596780/(1x49)
LCM = 39058596780/49
LCM = 797114220
Thus, we can understand that the LCM of 707,817,105,644 is 797114220.
