Given numbers are 157,978,767,507,949
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,978,767,507,949 is 111763523118.
Find LCM of 157,978,767,507,949 with Prime Factorization
| 3 | 157, 978, 767, 507, 949 |
| 13 | 157, 326, 767, 169, 949 |
| 157, 326, 59, 13, 73 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 157 x 326 x 59 x 13 x 73 = 111763523118
Therefore, the lowest common multiple of 157,978,767,507,949 is 111763523118.
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.
157 x 978 x 767 x 507 x 949 = 56664106220826
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.
157 : 1, 157
978 : 1, 2, 3, 6, 163, 326, 489, 978
767 : 1, 13, 59, 767
507 : 1, 3, 13, 39, 169, 507
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,978,767,507,949, is 1.
Now, the common factors can be found like this.
157:157
978:2x 3x 163
767:13x 59
507:3x 13x 13
949:13x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 13 = 507
Therefore, the value for common factors is 507.
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 = 56664106220826/(1x507)
LCM = 56664106220826/507
LCM = 111763523118
Thus, we can understand that the LCM of 157,978,767,507,949 is 111763523118.
