Find LCM of 688,930,581,973,488 with Prime Factorization
2 | 688, 930, 581, 973, 488 |
2 | 344, 465, 581, 973, 244 |
2 | 172, 465, 581, 973, 122 |
7 | 86, 465, 581, 973, 61 |
86, 465, 83, 139, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 86 x 465 x 83 x 139 x 61 = 1576021576080
Therefore, the lowest common multiple of 688,930,581,973,488 is 1576021576080.
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.
688 x 930 x 581 x 973 x 488 = 176514416520960
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
581 : 1, 7, 83, 581
973 : 1, 7, 139, 973
488 : 1, 2, 4, 8, 61, 122, 244, 488
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,930,581,973,488, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
930:2x 3x 5x 31
581:7x 83
973:7x 139
488:2x 2x 2x 61
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 7 = 112
Therefore, the value for common factors is 112.
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 = 176514416520960/(1x112)
LCM = 176514416520960/112
LCM = 1576021576080
Thus, we can understand that the LCM of 688,930,581,973,488 is 1576021576080.
