Given numbers are 545,782,360,374,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,782,360,374,821 is 138561188040.
Find LCM of 545,782,360,374,821 with Prime Factorization
| 2 | 545, 782, 360, 374, 821 |
| 5 | 545, 391, 180, 187, 821 |
| 17 | 109, 391, 36, 187, 821 |
| 109, 23, 36, 11, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 109 x 23 x 36 x 11 x 821 = 138561188040
Therefore, the lowest common multiple of 545,782,360,374,821 is 138561188040.
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.
545 x 782 x 360 x 374 x 821 = 47110803933600
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.
545 : 1, 5, 109, 545
782 : 1, 2, 17, 23, 34, 46, 391, 782
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
374 : 1, 2, 11, 17, 22, 34, 187, 374
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,782,360,374,821, is 1.
Now, the common factors can be found like this.
545:5x 109
782:2x 17x 23
360:2x 2x 2x 3x 3x 5
374:2x 11x 17
821:821
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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 47110803933600/(1x340)
LCM = 47110803933600/340
LCM = 138561188040
Thus, we can understand that the LCM of 545,782,360,374,821 is 138561188040.
