Given numbers are 701,491,531,138,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 701,491,531,138,742 is 3119074674786.
Find LCM of 701,491,531,138,742 with Prime Factorization
| 2 | 701, 491, 531, 138, 742 |
| 3 | 701, 491, 531, 69, 371 |
| 701, 491, 177, 23, 371 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 701 x 491 x 177 x 23 x 371 = 3119074674786
Therefore, the lowest common multiple of 701,491,531,138,742 is 3119074674786.
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.
701 x 491 x 531 x 138 x 742 = 18714448048716
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.
701 : 1, 701
491 : 1, 491
531 : 1, 3, 9, 59, 177, 531
138 : 1, 2, 3, 6, 23, 46, 69, 138
742 : 1, 2, 7, 14, 53, 106, 371, 742
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 701,491,531,138,742, is 1.
Now, the common factors can be found like this.
701:701
491:491
531:3x 3x 59
138:2x 3x 23
742:2x 7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 18714448048716/(1x6)
LCM = 18714448048716/6
LCM = 3119074674786
Thus, we can understand that the LCM of 701,491,531,138,742 is 3119074674786.
