Find LCM of 802,420,756,612 with Prime Factorization
2 | 802, 420, 756, 612 |
2 | 401, 210, 378, 306 |
3 | 401, 105, 189, 153 |
3 | 401, 35, 63, 51 |
7 | 401, 35, 21, 17 |
401, 5, 3, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 401 x 5 x 3 x 17 = 25768260
Therefore, the lowest common multiple of 802,420,756,612 is 25768260.
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.
802 x 420 x 756 x 612 = 155846436480
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.
802 : 1, 2, 401, 802
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,420,756,612, is 2.
Now, the common factors can be found like this.
802:2x 401
420:2x 2x 3x 5x 7
756:2x 2x 3x 3x 3x 7
612:2x 2x 3x 3x 17
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 2x 3x 3x 3x 7 = 3024
Therefore, the value for common factors is 3024.
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 = 155846436480/(2x3024)
LCM = 155846436480/6048
LCM = 25768260
Thus, we can understand that the LCM of 802,420,756,612 is 25768260.
