Given numbers are 645,292,473,213
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 645,292,473,213 is 147093540.
Find LCM of 645,292,473,213 with Prime Factorization
3 | 645, 292, 473, 213 |
43 | 215, 292, 473, 71 |
5, 292, 11, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 5 x 292 x 11 x 71 = 147093540
Therefore, the lowest common multiple of 645,292,473,213 is 147093540.
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.
645 x 292 x 473 x 213 = 18975066660
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
292 : 1, 2, 4, 73, 146, 292
473 : 1, 11, 43, 473
213 : 1, 3, 71, 213
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,292,473,213, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
292:2x 2x 73
473:11x 43
213:3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 18975066660/(1x129)
LCM = 18975066660/129
LCM = 147093540
Thus, we can understand that the LCM of 645,292,473,213 is 147093540.
