Given numbers are 550,645,129,570
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 550,645,129,570 is 1348050.
Find LCM of 550,645,129,570 with Prime Factorization
| 2 | 550, 645, 129, 570 |
| 3 | 275, 645, 129, 285 |
| 5 | 275, 215, 43, 95 |
| 43 | 55, 43, 43, 19 |
| 55, 1, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 43 x 55 x 1 x 1 x 19 = 1348050
Therefore, the lowest common multiple of 550,645,129,570 is 1348050.
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.
550 x 645 x 129 x 570 = 26084767500
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.
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
645 : 1, 3, 5, 15, 43, 129, 215, 645
129 : 1, 3, 43, 129
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,645,129,570, is 1.
Now, the common factors can be found like this.
550:2x 5x 5x 11
645:3x 5x 43
129:3x 43
570:2x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5x 43 = 19350
Therefore, the value for common factors is 19350.
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 = 26084767500/(1x19350)
LCM = 26084767500/19350
LCM = 1348050
Thus, we can understand that the LCM of 550,645,129,570 is 1348050.
