Given numbers are 707,342,791,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 707,342,791,615 is 5601158010.
Find LCM of 707,342,791,615 with Prime Factorization
| 3 | 707, 342, 791, 615 |
| 7 | 707, 114, 791, 205 |
| 101, 114, 113, 205 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 101 x 114 x 113 x 205 = 5601158010
Therefore, the lowest common multiple of 707,342,791,615 is 5601158010.
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 342 x 791 x 615 = 117624318210
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
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
791 : 1, 7, 113, 791
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,342,791,615, is 1.
Now, the common factors can be found like this.
707:7x 101
342:2x 3x 3x 19
791:7x 113
615:3x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 117624318210/(1x21)
LCM = 117624318210/21
LCM = 5601158010
Thus, we can understand that the LCM of 707,342,791,615 is 5601158010.
