Given numbers are 541,128,290,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 541,128,290,620 is 311269760.
Find LCM of 541,128,290,620 with Prime Factorization
2 | 541, 128, 290, 620 |
2 | 541, 64, 145, 310 |
5 | 541, 32, 145, 155 |
541, 32, 29, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 541 x 32 x 29 x 31 = 311269760
Therefore, the lowest common multiple of 541,128,290,620 is 311269760.
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.
541 x 128 x 290 x 620 = 12450790400
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.
541 : 1, 541
128 : 1, 2, 4, 8, 16, 32, 64, 128
290 : 1, 2, 5, 10, 29, 58, 145, 290
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 541,128,290,620, is 1.
Now, the common factors can be found like this.
541:541
128:2x 2x 2x 2x 2x 2x 2
290:2x 5x 29
620:2x 2x 5x 31
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 5 = 40
Therefore, the value for common factors is 40.
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 = 12450790400/(1x40)
LCM = 12450790400/40
LCM = 311269760
Thus, we can understand that the LCM of 541,128,290,620 is 311269760.
