Given numbers are 783,947,735,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 783,947,735,812 is 726670980.
Find LCM of 783,947,735,812 with Prime Factorization
3 | 783, 947, 735, 812 |
7 | 261, 947, 245, 812 |
29 | 261, 947, 35, 116 |
9, 947, 35, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 29 x 9 x 947 x 35 x 4 = 726670980
Therefore, the lowest common multiple of 783,947,735,812 is 726670980.
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.
783 x 947 x 735 x 812 = 442542626820
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
947 : 1, 947
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,947,735,812, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
947:947
735:3x 5x 7x 7
812:2x 2x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 29 = 609
Therefore, the value for common factors is 609.
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 = 442542626820/(1x609)
LCM = 442542626820/609
LCM = 726670980
Thus, we can understand that the LCM of 783,947,735,812 is 726670980.
