Given numbers are 741,988,787,623
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,988,787,623 is 1453252164.
Find LCM of 741,988,787,623 with Prime Factorization
| 13 | 741, 988, 787, 623 |
| 19 | 57, 76, 787, 623 |
| 3, 4, 787, 623 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 3 x 4 x 787 x 623 = 1453252164
Therefore, the lowest common multiple of 741,988,787,623 is 1453252164.
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.
741 x 988 x 787 x 623 = 358953284508
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
787 : 1, 787
623 : 1, 7, 89, 623
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,988,787,623, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
988:2x 2x 13x 19
787:787
623:7x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 358953284508/(1x247)
LCM = 358953284508/247
LCM = 1453252164
Thus, we can understand that the LCM of 741,988,787,623 is 1453252164.
