Find LCM of 421,969,798,702,212 with Prime Factorization
2 | 421, 969, 798, 702, 212 |
3 | 421, 969, 399, 351, 106 |
19 | 421, 323, 133, 117, 106 |
421, 17, 7, 117, 106 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 421 x 17 x 7 x 117 x 106 = 70831368972
Therefore, the lowest common multiple of 421,969,798,702,212 is 70831368972.
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.
421 x 969 x 798 x 702 x 212 = 48448656376848
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.
421 : 1, 421
969 : 1, 3, 17, 19, 51, 57, 323, 969
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
212 : 1, 2, 4, 53, 106, 212
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,969,798,702,212, is 1.
Now, the common factors can be found like this.
421:421
969:3x 17x 19
798:2x 3x 7x 19
702:2x 3x 3x 3x 13
212:2x 2x 53
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 19 = 684
Therefore, the value for common factors is 684.
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 = 48448656376848/(1x684)
LCM = 48448656376848/684
LCM = 70831368972
Thus, we can understand that the LCM of 421,969,798,702,212 is 70831368972.
