Given numbers are 698,528,920,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,528,920,680 is 360251760.
Find LCM of 698,528,920,680 with Prime Factorization
| 2 | 698, 528, 920, 680 |
| 2 | 349, 264, 460, 340 |
| 2 | 349, 132, 230, 170 |
| 5 | 349, 66, 115, 85 |
| 349, 66, 23, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 349 x 66 x 23 x 17 = 360251760
Therefore, the lowest common multiple of 698,528,920,680 is 360251760.
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.
698 x 528 x 920 x 680 = 230561126400
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.
698 : 1, 2, 349, 698
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,528,920,680, is 2.
Now, the common factors can be found like this.
698:2x 349
528:2x 2x 2x 2x 3x 11
920:2x 2x 2x 5x 23
680:2x 2x 2x 5x 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 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 230561126400/(2x320)
LCM = 230561126400/640
LCM = 360251760
Thus, we can understand that the LCM of 698,528,920,680 is 360251760.
