Given numbers are 437,391,969,470
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,391,969,470 is 10474890.
Find LCM of 437,391,969,470 with Prime Factorization
17 | 437, 391, 969, 470 |
19 | 437, 23, 57, 470 |
23 | 23, 23, 3, 470 |
1, 1, 3, 470 |
Multiply the prime numbers at the bottom and the left side.
17 x 19 x 23 x 1 x 1 x 3 x 470 = 10474890
Therefore, the lowest common multiple of 437,391,969,470 is 10474890.
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.
437 x 391 x 969 x 470 = 77817957810
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.
437 : 1, 19, 23, 437
391 : 1, 17, 23, 391
969 : 1, 3, 17, 19, 51, 57, 323, 969
470 : 1, 2, 5, 10, 47, 94, 235, 470
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,391,969,470, is 1.
Now, the common factors can be found like this.
437:19x 23
391:17x 23
969:3x 17x 19
470:2x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 19x 23 = 7429
Therefore, the value for common factors is 7429.
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 = 77817957810/(1x7429)
LCM = 77817957810/7429
LCM = 10474890
Thus, we can understand that the LCM of 437,391,969,470 is 10474890.
