Given numbers are 701,398,721,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 701,398,721,546 is 7845144762.
Find LCM of 701,398,721,546 with Prime Factorization
| 2 | 701, 398, 721, 546 |
| 7 | 701, 199, 721, 273 |
| 701, 199, 103, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 701 x 199 x 103 x 39 = 7845144762
Therefore, the lowest common multiple of 701,398,721,546 is 7845144762.
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 398 x 721 x 546 = 109832026668
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
398 : 1, 2, 199, 398
721 : 1, 7, 103, 721
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 701,398,721,546, is 1.
Now, the common factors can be found like this.
701:701
398:2x 199
721:7x 103
546:2x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 109832026668/(1x14)
LCM = 109832026668/14
LCM = 7845144762
Thus, we can understand that the LCM of 701,398,721,546 is 7845144762.
