Find LCM of 784,441,651,664,210 with Prime Factorization
2 | 784, 441, 651, 664, 210 |
2 | 392, 441, 651, 332, 105 |
2 | 196, 441, 651, 166, 105 |
3 | 98, 441, 651, 83, 105 |
7 | 98, 147, 217, 83, 35 |
7 | 14, 21, 31, 83, 5 |
2, 3, 31, 83, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 7 x 2 x 3 x 31 x 83 x 5 = 90775440
Therefore, the lowest common multiple of 784,441,651,664,210 is 90775440.
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.
784 x 441 x 651 x 664 x 210 = 31385063727360
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
651 : 1, 3, 7, 21, 31, 93, 217, 651
664 : 1, 2, 4, 8, 83, 166, 332, 664
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,441,651,664,210, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
441:3x 3x 7x 7
651:3x 7x 31
664:2x 2x 2x 83
210:2x 3x 5x 7
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 7x 7x 7x 7 = 345744
Therefore, the value for common factors is 345744.
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 = 31385063727360/(1x345744)
LCM = 31385063727360/345744
LCM = 90775440
Thus, we can understand that the LCM of 784,441,651,664,210 is 90775440.
