Given numbers are 437,420,988,413
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,420,988,413 is 140775180.
Find LCM of 437,420,988,413 with Prime Factorization
2 | 437, 420, 988, 413 |
2 | 437, 210, 494, 413 |
7 | 437, 105, 247, 413 |
19 | 437, 15, 247, 59 |
23, 15, 13, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 23 x 15 x 13 x 59 = 140775180
Therefore, the lowest common multiple of 437,420,988,413 is 140775180.
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 420 x 988 x 413 = 74892395760
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
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
413 : 1, 7, 59, 413
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,420,988,413, is 1.
Now, the common factors can be found like this.
437:19x 23
420:2x 2x 3x 5x 7
988:2x 2x 13x 19
413:7x 59
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 7x 19 = 532
Therefore, the value for common factors is 532.
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 = 74892395760/(1x532)
LCM = 74892395760/532
LCM = 140775180
Thus, we can understand that the LCM of 437,420,988,413 is 140775180.
