Given numbers are 647,782,334,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,782,334,155 is 13096619290.
Find LCM of 647,782,334,155 with Prime Factorization
| 2 | 647, 782, 334, 155 |
| 647, 391, 167, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 647 x 391 x 167 x 155 = 13096619290
Therefore, the lowest common multiple of 647,782,334,155 is 13096619290.
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.
647 x 782 x 334 x 155 = 26193238580
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.
647 : 1, 647
782 : 1, 2, 17, 23, 34, 46, 391, 782
334 : 1, 2, 167, 334
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,782,334,155, is 1.
Now, the common factors can be found like this.
647:647
782:2x 17x 23
334:2x 167
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 26193238580/(1x2)
LCM = 26193238580/2
LCM = 13096619290
Thus, we can understand that the LCM of 647,782,334,155 is 13096619290.
