Given numbers are 784,761,291,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,761,291,909 is 52606127952.
Find LCM of 784,761,291,909 with Prime Factorization
| 3 | 784, 761, 291, 909 |
| 784, 761, 97, 303 |
Multiply the prime numbers at the bottom and the left side.
3 x 784 x 761 x 97 x 303 = 52606127952
Therefore, the lowest common multiple of 784,761,291,909 is 52606127952.
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.
784 x 761 x 291 x 909 = 157818383856
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
761 : 1, 761
291 : 1, 3, 97, 291
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,761,291,909, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
761:761
291:3x 97
909:3x 3x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 157818383856/(1x3)
LCM = 157818383856/3
LCM = 52606127952
Thus, we can understand that the LCM of 784,761,291,909 is 52606127952.
