Given numbers are 772,175,744,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 772,175,744,620 is 25128600.
Find LCM of 772,175,744,620 with Prime Factorization
| 2 | 772, 175, 744, 620 |
| 2 | 386, 175, 372, 310 |
| 5 | 193, 175, 186, 155 |
| 31 | 193, 35, 186, 31 |
| 193, 35, 6, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 31 x 193 x 35 x 6 x 1 = 25128600
Therefore, the lowest common multiple of 772,175,744,620 is 25128600.
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 175 x 744 x 620 = 62318928000
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
175 : 1, 5, 7, 25, 35, 175
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,175,744,620, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
175:5x 5x 7
744:2x 2x 2x 3x 31
620:2x 2x 5x 31
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 5x 31 = 2480
Therefore, the value for common factors is 2480.
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 = 62318928000/(1x2480)
LCM = 62318928000/2480
LCM = 25128600
Thus, we can understand that the LCM of 772,175,744,620 is 25128600.
