Given numbers are 142,604,209,679,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,604,209,679,665 is 30428556620.
Find LCM of 142,604,209,679,665 with Prime Factorization
| 2 | 142, 604, 209, 679, 665 |
| 7 | 71, 302, 209, 679, 665 |
| 19 | 71, 302, 209, 97, 95 |
| 71, 302, 11, 97, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 71 x 302 x 11 x 97 x 5 = 30428556620
Therefore, the lowest common multiple of 142,604,209,679,665 is 30428556620.
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.
142 x 604 x 209 x 679 x 665 = 8093996060920
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.
142 : 1, 2, 71, 142
604 : 1, 2, 4, 151, 302, 604
209 : 1, 11, 19, 209
679 : 1, 7, 97, 679
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,604,209,679,665, is 1.
Now, the common factors can be found like this.
142:2x 71
604:2x 2x 151
209:11x 19
679:7x 97
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 19 = 266
Therefore, the value for common factors is 266.
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 = 8093996060920/(1x266)
LCM = 8093996060920/266
LCM = 30428556620
Thus, we can understand that the LCM of 142,604,209,679,665 is 30428556620.
