Given numbers are 751,807,980,247,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 751,807,980,247,956 is 35061815623380.
Find LCM of 751,807,980,247,956 with Prime Factorization
| 2 | 751, 807, 980, 247, 956 |
| 2 | 751, 807, 490, 247, 478 |
| 751, 807, 245, 247, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 751 x 807 x 245 x 247 x 239 = 35061815623380
Therefore, the lowest common multiple of 751,807,980,247,956 is 35061815623380.
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.
751 x 807 x 980 x 247 x 956 = 140247262493520
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.
751 : 1, 751
807 : 1, 3, 269, 807
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
247 : 1, 13, 19, 247
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,807,980,247,956, is 1.
Now, the common factors can be found like this.
751:751
807:3x 269
980:2x 2x 5x 7x 7
247:13x 19
956:2x 2x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 140247262493520/(1x4)
LCM = 140247262493520/4
LCM = 35061815623380
Thus, we can understand that the LCM of 751,807,980,247,956 is 35061815623380.
