Given numbers are 697,126,382,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,126,382,407 is 6827018814.
Find LCM of 697,126,382,407 with Prime Factorization
| 2 | 697, 126, 382, 407 |
| 697, 63, 191, 407 |
Multiply the prime numbers at the bottom and the left side.
2 x 697 x 63 x 191 x 407 = 6827018814
Therefore, the lowest common multiple of 697,126,382,407 is 6827018814.
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.
697 x 126 x 382 x 407 = 13654037628
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.
697 : 1, 17, 41, 697
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
382 : 1, 2, 191, 382
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,126,382,407, is 1.
Now, the common factors can be found like this.
697:17x 41
126:2x 3x 3x 7
382:2x 191
407:11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 13654037628/(1x2)
LCM = 13654037628/2
LCM = 6827018814
Thus, we can understand that the LCM of 697,126,382,407 is 6827018814.
