Given numbers are 690,211,633,733
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,211,633,733 is 106717470.
Find LCM of 690,211,633,733 with Prime Factorization
| 3 | 690, 211, 633, 733 |
| 211 | 230, 211, 211, 733 |
| 230, 1, 1, 733 |
Multiply the prime numbers at the bottom and the left side.
3 x 211 x 230 x 1 x 1 x 733 = 106717470
Therefore, the lowest common multiple of 690,211,633,733 is 106717470.
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.
690 x 211 x 633 x 733 = 67552158510
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
211 : 1, 211
633 : 1, 3, 211, 633
733 : 1, 733
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,211,633,733, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
211:211
633:3x 211
733:733
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 211 = 633
Therefore, the value for common factors is 633.
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 = 67552158510/(1x633)
LCM = 67552158510/633
LCM = 106717470
Thus, we can understand that the LCM of 690,211,633,733 is 106717470.
