Find LCM of 972,155,437,552 with Prime Factorization
| 2 | 972, 155, 437, 552 |
| 2 | 486, 155, 437, 276 |
| 3 | 243, 155, 437, 138 |
| 23 | 81, 155, 437, 46 |
| 81, 155, 19, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 81 x 155 x 19 x 2 = 131676840
Therefore, the lowest common multiple of 972,155,437,552 is 131676840.
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.
972 x 155 x 437 x 552 = 36342807840
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
155 : 1, 5, 31, 155
437 : 1, 19, 23, 437
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,155,437,552, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
155:5x 31
437:19x 23
552:2x 2x 2x 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 23 = 276
Therefore, the value for common factors is 276.
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 = 36342807840/(1x276)
LCM = 36342807840/276
LCM = 131676840
Thus, we can understand that the LCM of 972,155,437,552 is 131676840.
