Given numbers are 694,665,154,978,852
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 694,665,154,978,852 is 352509645180.
Find LCM of 694,665,154,978,852 with Prime Factorization
| 2 | 694, 665, 154, 978, 852 |
| 3 | 347, 665, 77, 489, 426 |
| 7 | 347, 665, 77, 163, 142 |
| 347, 95, 11, 163, 142 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 347 x 95 x 11 x 163 x 142 = 352509645180
Therefore, the lowest common multiple of 694,665,154,978,852 is 352509645180.
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.
694 x 665 x 154 x 978 x 852 = 59221620390240
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.
694 : 1, 2, 347, 694
665 : 1, 5, 7, 19, 35, 95, 133, 665
154 : 1, 2, 7, 11, 14, 22, 77, 154
978 : 1, 2, 3, 6, 163, 326, 489, 978
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,665,154,978,852, is 1.
Now, the common factors can be found like this.
694:2x 347
665:5x 7x 19
154:2x 7x 11
978:2x 3x 163
852:2x 2x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 59221620390240/(1x168)
LCM = 59221620390240/168
LCM = 352509645180
Thus, we can understand that the LCM of 694,665,154,978,852 is 352509645180.
