Given numbers are 250,965,978,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 250,965,978,661 is 15595799250.
Find LCM of 250,965,978,661 with Prime Factorization
| 2 | 250, 965, 978, 661 |
| 5 | 125, 965, 489, 661 |
| 25, 193, 489, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 25 x 193 x 489 x 661 = 15595799250
Therefore, the lowest common multiple of 250,965,978,661 is 15595799250.
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.
250 x 965 x 978 x 661 = 155957992500
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.
250 : 1, 2, 5, 10, 25, 50, 125, 250
965 : 1, 5, 193, 965
978 : 1, 2, 3, 6, 163, 326, 489, 978
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 250,965,978,661, is 1.
Now, the common factors can be found like this.
250:2x 5x 5x 5
965:5x 193
978:2x 3x 163
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 155957992500/(1x10)
LCM = 155957992500/10
LCM = 15595799250
Thus, we can understand that the LCM of 250,965,978,661 is 15595799250.
