Given numbers are 619,734,945,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,734,945,690 is 9875210310.
Find LCM of 619,734,945,690 with Prime Factorization
| 2 | 619, 734, 945, 690 |
| 3 | 619, 367, 945, 345 |
| 5 | 619, 367, 315, 115 |
| 619, 367, 63, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 619 x 367 x 63 x 23 = 9875210310
Therefore, the lowest common multiple of 619,734,945,690 is 9875210310.
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.
619 x 734 x 945 x 690 = 296256309300
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.
619 : 1, 619
734 : 1, 2, 367, 734
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,734,945,690, is 1.
Now, the common factors can be found like this.
619:619
734:2x 367
945:3x 3x 3x 5x 7
690:2x 3x 5x 23
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 5 = 30
Therefore, the value for common factors is 30.
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 = 296256309300/(1x30)
LCM = 296256309300/30
LCM = 9875210310
Thus, we can understand that the LCM of 619,734,945,690 is 9875210310.
