Given numbers are 145,956,507,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 145,956,507,220 is 773083740.
Find LCM of 145,956,507,220 with Prime Factorization
| 2 | 145, 956, 507, 220 |
| 2 | 145, 478, 507, 110 |
| 5 | 145, 239, 507, 55 |
| 29, 239, 507, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 239 x 507 x 11 = 773083740
Therefore, the lowest common multiple of 145,956,507,220 is 773083740.
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.
145 x 956 x 507 x 220 = 15461674800
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.
145 : 1, 5, 29, 145
956 : 1, 2, 4, 239, 478, 956
507 : 1, 3, 13, 39, 169, 507
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 145,956,507,220, is 1.
Now, the common factors can be found like this.
145:5x 29
956:2x 2x 239
507:3x 13x 13
220:2x 2x 5x 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 2x 5 = 20
Therefore, the value for common factors is 20.
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 = 15461674800/(1x20)
LCM = 15461674800/20
LCM = 773083740
Thus, we can understand that the LCM of 145,956,507,220 is 773083740.
