Given numbers are 781,346,974,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,346,974,681 is 89619642222.
Find LCM of 781,346,974,681 with Prime Factorization
| 2 | 781, 346, 974, 681 |
| 781, 173, 487, 681 |
Multiply the prime numbers at the bottom and the left side.
2 x 781 x 173 x 487 x 681 = 89619642222
Therefore, the lowest common multiple of 781,346,974,681 is 89619642222.
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 346 x 974 x 681 = 179239284444
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
346 : 1, 2, 173, 346
974 : 1, 2, 487, 974
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,346,974,681, is 1.
Now, the common factors can be found like this.
781:11x 71
346:2x 173
974:2x 487
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 179239284444/(1x2)
LCM = 179239284444/2
LCM = 89619642222
Thus, we can understand that the LCM of 781,346,974,681 is 89619642222.
