Given numbers are 637,209,466,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,209,466,770 is 310199890.
Find LCM of 637,209,466,770 with Prime Factorization
| 2 | 637, 209, 466, 770 |
| 7 | 637, 209, 233, 385 |
| 11 | 91, 209, 233, 55 |
| 91, 19, 233, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 91 x 19 x 233 x 5 = 310199890
Therefore, the lowest common multiple of 637,209,466,770 is 310199890.
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.
637 x 209 x 466 x 770 = 47770783060
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.
637 : 1, 7, 13, 49, 91, 637
209 : 1, 11, 19, 209
466 : 1, 2, 233, 466
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,209,466,770, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
209:11x 19
466:2x 233
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
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 = 47770783060/(1x154)
LCM = 47770783060/154
LCM = 310199890
Thus, we can understand that the LCM of 637,209,466,770 is 310199890.
