Find LCM of 377,663,390,745,972 with Prime Factorization
| 2 | 377, 663, 390, 745, 972 |
| 3 | 377, 663, 195, 745, 486 |
| 5 | 377, 221, 65, 745, 162 |
| 13 | 377, 221, 13, 149, 162 |
| 29, 17, 1, 149, 162 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 29 x 17 x 1 x 149 x 162 = 4641013260
Therefore, the lowest common multiple of 377,663,390,745,972 is 4641013260.
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.
377 x 663 x 390 x 745 x 972 = 70589811684600
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.
377 : 1, 13, 29, 377
663 : 1, 3, 13, 17, 39, 51, 221, 663
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
745 : 1, 5, 149, 745
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 377,663,390,745,972, is 1.
Now, the common factors can be found like this.
377:13x 29
663:3x 13x 17
390:2x 3x 5x 13
745:5x 149
972:2x 2x 3x 3x 3x 3x 3
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 13x 13 = 15210
Therefore, the value for common factors is 15210.
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 = 70589811684600/(1x15210)
LCM = 70589811684600/15210
LCM = 4641013260
Thus, we can understand that the LCM of 377,663,390,745,972 is 4641013260.
