Given numbers are 781,906,649,604
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,906,649,604 is 83495148.
Find LCM of 781,906,649,604 with Prime Factorization
2 | 781, 906, 649, 604 |
11 | 781, 453, 649, 302 |
151 | 71, 453, 59, 302 |
71, 3, 59, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 151 x 71 x 3 x 59 x 2 = 83495148
Therefore, the lowest common multiple of 781,906,649,604 is 83495148.
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.
781 x 906 x 649 x 604 = 277370881656
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.
781 : 1, 11, 71, 781
906 : 1, 2, 3, 6, 151, 302, 453, 906
649 : 1, 11, 59, 649
604 : 1, 2, 4, 151, 302, 604
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,906,649,604, is 1.
Now, the common factors can be found like this.
781:11x 71
906:2x 3x 151
649:11x 59
604:2x 2x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 151 = 3322
Therefore, the value for common factors is 3322.
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 = 277370881656/(1x3322)
LCM = 277370881656/3322
LCM = 83495148
Thus, we can understand that the LCM of 781,906,649,604 is 83495148.
