Given numbers are 344,665,604,679,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 344,665,604,679,421 is 1410622690120.
Find LCM of 344,665,604,679,421 with Prime Factorization
| 2 | 344, 665, 604, 679, 421 |
| 2 | 172, 665, 302, 679, 421 |
| 7 | 86, 665, 151, 679, 421 |
| 86, 95, 151, 97, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 86 x 95 x 151 x 97 x 421 = 1410622690120
Therefore, the lowest common multiple of 344,665,604,679,421 is 1410622690120.
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.
344 x 665 x 604 x 679 x 421 = 39497435323360
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.
344 : 1, 2, 4, 8, 43, 86, 172, 344
665 : 1, 5, 7, 19, 35, 95, 133, 665
604 : 1, 2, 4, 151, 302, 604
679 : 1, 7, 97, 679
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 344,665,604,679,421, is 1.
Now, the common factors can be found like this.
344:2x 2x 2x 43
665:5x 7x 19
604:2x 2x 151
679:7x 97
421:421
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 7 = 28
Therefore, the value for common factors is 28.
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 = 39497435323360/(1x28)
LCM = 39497435323360/28
LCM = 1410622690120
Thus, we can understand that the LCM of 344,665,604,679,421 is 1410622690120.
