Given numbers are 784,871,163,676
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,871,163,676 is 1446988816.
Find LCM of 784,871,163,676 with Prime Factorization
2 | 784, 871, 163, 676 |
2 | 392, 871, 163, 338 |
13 | 196, 871, 163, 169 |
196, 67, 163, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 196 x 67 x 163 x 13 = 1446988816
Therefore, the lowest common multiple of 784,871,163,676 is 1446988816.
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.
784 x 871 x 163 x 676 = 75243418432
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
871 : 1, 13, 67, 871
163 : 1, 163
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,871,163,676, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
871:13x 67
163:163
676:2x 2x 13x 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 13 = 52
Therefore, the value for common factors is 52.
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 = 75243418432/(1x52)
LCM = 75243418432/52
LCM = 1446988816
Thus, we can understand that the LCM of 784,871,163,676 is 1446988816.
