Given numbers are 630,780,802,375
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 630,780,802,375 is 164209500.
Find LCM of 630,780,802,375 with Prime Factorization
| 2 | 630, 780, 802, 375 |
| 3 | 315, 390, 401, 375 |
| 5 | 105, 130, 401, 125 |
| 21, 26, 401, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 21 x 26 x 401 x 25 = 164209500
Therefore, the lowest common multiple of 630,780,802,375 is 164209500.
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.
630 x 780 x 802 x 375 = 147788550000
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
802 : 1, 2, 401, 802
375 : 1, 3, 5, 15, 25, 75, 125, 375
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,780,802,375, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
780:2x 2x 3x 5x 13
802:2x 401
375:3x 5x 5x 5
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 3x 3x 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 147788550000/(1x900)
LCM = 147788550000/900
LCM = 164209500
Thus, we can understand that the LCM of 630,780,802,375 is 164209500.
