Given numbers are 437,988,690,542
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,988,690,542 is 92373060.
Find LCM of 437,988,690,542 with Prime Factorization
| 2 | 437, 988, 690, 542 |
| 19 | 437, 494, 345, 271 |
| 23 | 23, 26, 345, 271 |
| 1, 26, 15, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 23 x 1 x 26 x 15 x 271 = 92373060
Therefore, the lowest common multiple of 437,988,690,542 is 92373060.
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 988 x 690 x 542 = 161468108880
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
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
542 : 1, 2, 271, 542
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,988,690,542, is 1.
Now, the common factors can be found like this.
437:19x 23
988:2x 2x 13x 19
690:2x 3x 5x 23
542:2x 271
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 19x 23 = 1748
Therefore, the value for common factors is 1748.
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 = 161468108880/(1x1748)
LCM = 161468108880/1748
LCM = 92373060
Thus, we can understand that the LCM of 437,988,690,542 is 92373060.
