Given numbers are 390,220,474,377,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 390,220,474,377,765 is 1002495780.
Find LCM of 390,220,474,377,765 with Prime Factorization
| 2 | 390, 220, 474, 377, 765 |
| 3 | 195, 110, 237, 377, 765 |
| 5 | 65, 110, 79, 377, 255 |
| 13 | 13, 22, 79, 377, 51 |
| 1, 22, 79, 29, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 1 x 22 x 79 x 29 x 51 = 1002495780
Therefore, the lowest common multiple of 390,220,474,377,765 is 1002495780.
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.
390 x 220 x 474 x 377 x 765 = 11729200626000
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
474 : 1, 2, 3, 6, 79, 158, 237, 474
377 : 1, 13, 29, 377
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,220,474,377,765, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
220:2x 2x 5x 11
474:2x 3x 79
377:13x 29
765:3x 3x 5x 17
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 3x 5x 5x 13 = 11700
Therefore, the value for common factors is 11700.
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 = 11729200626000/(1x11700)
LCM = 11729200626000/11700
LCM = 1002495780
Thus, we can understand that the LCM of 390,220,474,377,765 is 1002495780.
