Given numbers are 578,157,785,778
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,157,785,778 is 176500970.
Find LCM of 578,157,785,778 with Prime Factorization
2 | 578, 157, 785, 778 |
157 | 289, 157, 785, 389 |
289, 1, 5, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 157 x 289 x 1 x 5 x 389 = 176500970
Therefore, the lowest common multiple of 578,157,785,778 is 176500970.
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.
578 x 157 x 785 x 778 = 55421304580
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.
578 : 1, 2, 17, 34, 289, 578
157 : 1, 157
785 : 1, 5, 157, 785
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,157,785,778, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
157:157
785:5x 157
778:2x 389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 157 = 314
Therefore, the value for common factors is 314.
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 = 55421304580/(1x314)
LCM = 55421304580/314
LCM = 176500970
Thus, we can understand that the LCM of 578,157,785,778 is 176500970.
