Given numbers are 752,676,781,156
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 752,676,781,156 is 297767184.
Find LCM of 752,676,781,156 with Prime Factorization
2 | 752, 676, 781, 156 |
2 | 376, 338, 781, 78 |
13 | 188, 169, 781, 39 |
188, 13, 781, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 188 x 13 x 781 x 3 = 297767184
Therefore, the lowest common multiple of 752,676,781,156 is 297767184.
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.
752 x 676 x 781 x 156 = 61935574272
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.
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
781 : 1, 11, 71, 781
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 752,676,781,156, is 1.
Now, the common factors can be found like this.
752:2x 2x 2x 2x 47
676:2x 2x 13x 13
781:11x 71
156:2x 2x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 13 = 208
Therefore, the value for common factors is 208.
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 = 61935574272/(1x208)
LCM = 61935574272/208
LCM = 297767184
Thus, we can understand that the LCM of 752,676,781,156 is 297767184.
