Given numbers are 642,697,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,697,493 is 12976746.
Find LCM of 642,697,493 with Prime Factorization
17 | 642, 697, 493 |
642, 41, 29 |
Multiply the prime numbers at the bottom and the left side.
17 x 642 x 41 x 29 = 12976746
Therefore, the lowest common multiple of 642,697,493 is 12976746.
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.
642 x 697 x 493 = 220604682
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
697 : 1, 17, 41, 697
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,697,493, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
697:17x 41
493:17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 220604682/(1x17)
LCM = 220604682/17
LCM = 12976746
Thus, we can understand that the LCM of 642,697,493 is 12976746.
