Given numbers are 710,780,949,538,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 710,780,949,538,309 is 112012197180.
Find LCM of 710,780,949,538,309 with Prime Factorization
| 2 | 710, 780, 949, 538, 309 |
| 3 | 355, 390, 949, 269, 309 |
| 5 | 355, 130, 949, 269, 103 |
| 13 | 71, 26, 949, 269, 103 |
| 71, 2, 73, 269, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 71 x 2 x 73 x 269 x 103 = 112012197180
Therefore, the lowest common multiple of 710,780,949,538,309 is 112012197180.
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.
710 x 780 x 949 x 538 x 309 = 87369513800400
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.
710 : 1, 2, 5, 10, 71, 142, 355, 710
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
949 : 1, 13, 73, 949
538 : 1, 2, 269, 538
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 710,780,949,538,309, is 1.
Now, the common factors can be found like this.
710:2x 5x 71
780:2x 2x 3x 5x 13
949:13x 73
538:2x 269
309:3x 103
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 3x 5x 13 = 780
Therefore, the value for common factors is 780.
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 = 87369513800400/(1x780)
LCM = 87369513800400/780
LCM = 112012197180
Thus, we can understand that the LCM of 710,780,949,538,309 is 112012197180.
