Given numbers are 478,661,702,765,173
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,661,702,765,173 is 1630802998890.
Find LCM of 478,661,702,765,173 with Prime Factorization
| 2 | 478, 661, 702, 765, 173 |
| 3 | 239, 661, 351, 765, 173 |
| 3 | 239, 661, 117, 255, 173 |
| 239, 661, 39, 85, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 239 x 661 x 39 x 85 x 173 = 1630802998890
Therefore, the lowest common multiple of 478,661,702,765,173 is 1630802998890.
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.
478 x 661 x 702 x 765 x 173 = 29354453980020
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.
478 : 1, 2, 239, 478
661 : 1, 661
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
173 : 1, 173
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,661,702,765,173, is 1.
Now, the common factors can be found like this.
478:2x 239
661:661
702:2x 3x 3x 3x 13
765:3x 3x 5x 17
173:173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 29354453980020/(1x18)
LCM = 29354453980020/18
LCM = 1630802998890
Thus, we can understand that the LCM of 478,661,702,765,173 is 1630802998890.
