Given numbers are 320,821,611,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 320,821,611,580 is 4655135680.
Find LCM of 320,821,611,580 with Prime Factorization
2 | 320, 821, 611, 580 |
2 | 160, 821, 611, 290 |
5 | 80, 821, 611, 145 |
16, 821, 611, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 16 x 821 x 611 x 29 = 4655135680
Therefore, the lowest common multiple of 320,821,611,580 is 4655135680.
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.
320 x 821 x 611 x 580 = 93102713600
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.
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
821 : 1, 821
611 : 1, 13, 47, 611
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,821,611,580, is 1.
Now, the common factors can be found like this.
320:2x 2x 2x 2x 2x 2x 5
821:821
611:13x 47
580:2x 2x 5x 29
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 5 = 20
Therefore, the value for common factors is 20.
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 = 93102713600/(1x20)
LCM = 93102713600/20
LCM = 4655135680
Thus, we can understand that the LCM of 320,821,611,580 is 4655135680.
