Find LCM of 781,775,859,372,946 with Prime Factorization
2 | 781, 775, 859, 372, 946 |
11 | 781, 775, 859, 186, 473 |
31 | 71, 775, 859, 186, 43 |
71, 25, 859, 6, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 31 x 71 x 25 x 859 x 6 x 43 = 268284512100
Therefore, the lowest common multiple of 781,775,859,372,946 is 268284512100.
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 775 x 859 x 372 x 946 = 182970037252200
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
775 : 1, 5, 25, 31, 155, 775
859 : 1, 859
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,775,859,372,946, is 1.
Now, the common factors can be found like this.
781:11x 71
775:5x 5x 31
859:859
372:2x 2x 3x 31
946:2x 11x 43
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 31 = 682
Therefore, the value for common factors is 682.
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 = 182970037252200/(1x682)
LCM = 182970037252200/682
LCM = 268284512100
Thus, we can understand that the LCM of 781,775,859,372,946 is 268284512100.
