Find LCM of 912,994,426,905,642 with Prime Factorization
2 | 912, 994, 426, 905, 642 |
3 | 456, 497, 213, 905, 321 |
71 | 152, 497, 71, 905, 107 |
152, 7, 1, 905, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 152 x 7 x 1 x 905 x 107 = 43891819440
Therefore, the lowest common multiple of 912,994,426,905,642 is 43891819440.
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.
912 x 994 x 426 x 905 x 642 = 224374980977280
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
994 : 1, 2, 7, 14, 71, 142, 497, 994
426 : 1, 2, 3, 6, 71, 142, 213, 426
905 : 1, 5, 181, 905
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,994,426,905,642, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
994:2x 7x 71
426:2x 3x 71
905:5x 181
642:2x 3x 107
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 3x 3x 71 = 5112
Therefore, the value for common factors is 5112.
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 = 224374980977280/(1x5112)
LCM = 224374980977280/5112
LCM = 43891819440
Thus, we can understand that the LCM of 912,994,426,905,642 is 43891819440.
