Given numbers are 972,363,780,107,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,363,780,107,628 is 128424659220.
Find LCM of 972,363,780,107,628 with Prime Factorization
| 2 | 972, 363, 780, 107, 628 |
| 2 | 486, 363, 390, 107, 314 |
| 3 | 243, 363, 195, 107, 157 |
| 81, 121, 65, 107, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 81 x 121 x 65 x 107 x 157 = 128424659220
Therefore, the lowest common multiple of 972,363,780,107,628 is 128424659220.
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 363 x 780 x 107 x 628 = 18493150927680
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
363 : 1, 3, 11, 33, 121, 363
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
107 : 1, 107
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,363,780,107,628, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
363:3x 11x 11
780:2x 2x 3x 5x 13
107:107
628:2x 2x 157
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 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 18493150927680/(1x144)
LCM = 18493150927680/144
LCM = 128424659220
Thus, we can understand that the LCM of 972,363,780,107,628 is 128424659220.
