Given numbers are 781,767,390,477
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,767,390,477 is 2857358790.
Find LCM of 781,767,390,477 with Prime Factorization
3 | 781, 767, 390, 477 |
13 | 781, 767, 130, 159 |
781, 59, 10, 159 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 781 x 59 x 10 x 159 = 2857358790
Therefore, the lowest common multiple of 781,767,390,477 is 2857358790.
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 767 x 390 x 477 = 111436992810
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
767 : 1, 13, 59, 767
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
477 : 1, 3, 9, 53, 159, 477
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,767,390,477, is 1.
Now, the common factors can be found like this.
781:11x 71
767:13x 59
390:2x 3x 5x 13
477:3x 3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 111436992810/(1x39)
LCM = 111436992810/39
LCM = 2857358790
Thus, we can understand that the LCM of 781,767,390,477 is 2857358790.
