Given numbers are 187,918,220,563,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 187,918,220,563,754 is 21433105980.
Find LCM of 187,918,220,563,754 with Prime Factorization
| 2 | 187, 918, 220, 563, 754 |
| 11 | 187, 459, 110, 563, 377 |
| 17 | 17, 459, 10, 563, 377 |
| 1, 27, 10, 563, 377 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 1 x 27 x 10 x 563 x 377 = 21433105980
Therefore, the lowest common multiple of 187,918,220,563,754 is 21433105980.
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.
187 x 918 x 220 x 563 x 754 = 16031963273040
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.
187 : 1, 11, 17, 187
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
563 : 1, 563
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,918,220,563,754, is 1.
Now, the common factors can be found like this.
187:11x 17
918:2x 3x 3x 3x 17
220:2x 2x 5x 11
563:563
754:2x 13x 29
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 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 16031963273040/(1x748)
LCM = 16031963273040/748
LCM = 21433105980
Thus, we can understand that the LCM of 187,918,220,563,754 is 21433105980.
