Given numbers are 772,132,921,149,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 772,132,921,149,748 is 19810927356.
Find LCM of 772,132,921,149,748 with Prime Factorization
| 2 | 772, 132, 921, 149, 748 |
| 2 | 386, 66, 921, 149, 374 |
| 3 | 193, 33, 921, 149, 187 |
| 11 | 193, 11, 307, 149, 187 |
| 193, 1, 307, 149, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 193 x 1 x 307 x 149 x 17 = 19810927356
Therefore, the lowest common multiple of 772,132,921,149,748 is 19810927356.
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.
772 x 132 x 921 x 149 x 748 = 10460169643968
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.
772 : 1, 2, 4, 193, 386, 772
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
921 : 1, 3, 307, 921
149 : 1, 149
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,132,921,149,748, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
132:2x 2x 3x 11
921:3x 307
149:149
748:2x 2x 11x 17
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 11 = 528
Therefore, the value for common factors is 528.
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 = 10460169643968/(1x528)
LCM = 10460169643968/528
LCM = 19810927356
Thus, we can understand that the LCM of 772,132,921,149,748 is 19810927356.
