Given numbers are 678,697,991,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,697,991,724 is 169529271972.
Find LCM of 678,697,991,724 with Prime Factorization
| 2 | 678, 697, 991, 724 |
| 339, 697, 991, 362 |
Multiply the prime numbers at the bottom and the left side.
2 x 339 x 697 x 991 x 362 = 169529271972
Therefore, the lowest common multiple of 678,697,991,724 is 169529271972.
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.
678 x 697 x 991 x 724 = 339058543944
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
697 : 1, 17, 41, 697
991 : 1, 991
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,697,991,724, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
697:17x 41
991:991
724:2x 2x 181
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 = 339058543944/(1x2)
LCM = 339058543944/2
LCM = 169529271972
Thus, we can understand that the LCM of 678,697,991,724 is 169529271972.
