Given numbers are 634,431,690,334,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,431,690,334,120 is 62974116840.
Find LCM of 634,431,690,334,120 with Prime Factorization
| 2 | 634, 431, 690, 334, 120 |
| 3 | 317, 431, 345, 167, 60 |
| 5 | 317, 431, 115, 167, 20 |
| 317, 431, 23, 167, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 317 x 431 x 23 x 167 x 4 = 62974116840
Therefore, the lowest common multiple of 634,431,690,334,120 is 62974116840.
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.
634 x 431 x 690 x 334 x 120 = 7556894020800
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.
634 : 1, 2, 317, 634
431 : 1, 431
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
334 : 1, 2, 167, 334
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,431,690,334,120, is 1.
Now, the common factors can be found like this.
634:2x 317
431:431
690:2x 3x 5x 23
334:2x 167
120:2x 2x 2x 3x 5
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 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 7556894020800/(1x120)
LCM = 7556894020800/120
LCM = 62974116840
Thus, we can understand that the LCM of 634,431,690,334,120 is 62974116840.
