The LCM of 361,144,639,564,621 is 11969471952.
Find LCM of 361,144,639,564,621 with Prime Factorization
| 2 | 361, 144, 639, 564, 621 |
| 2 | 361, 72, 639, 282, 621 |
| 3 | 361, 36, 639, 141, 621 |
| 3 | 361, 12, 213, 47, 207 |
| 361, 4, 71, 47, 69 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 361 x 4 x 71 x 47 x 69 = 11969471952
Therefore, the lowest common multiple of 361,144,639,564,621 is 11969471952.
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.
361 x 144 x 639 x 564 x 621 = 11634326737344
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.
361 : 1, 19, 361
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
639 : 1, 3, 9, 71, 213, 639
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,144,639,564,621, is 1.
Now, the common factors can be found like this.
361:19x 19
144:2x 2x 2x 2x 3x 3
639:3x 3x 71
564:2x 2x 3x 47
621:3x 3x 3x 23
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 3x 3x 3x 3x 3 = 972
Therefore, the value for common factors is 972.
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 = 11634326737344/(1x972)
LCM = 11634326737344/972
LCM = 11969471952
Thus, we can understand that the LCM of 361,144,639,564,621 is 11969471952.
