Find LCM of 558,245,142,639,938 with Prime Factorization
2 | 558, 245, 142, 639, 938 |
3 | 279, 245, 71, 639, 469 |
3 | 93, 245, 71, 213, 469 |
7 | 31, 245, 71, 71, 469 |
71 | 31, 35, 71, 71, 67 |
31, 35, 1, 1, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 71 x 31 x 35 x 1 x 1 x 67 = 650329470
Therefore, the lowest common multiple of 558,245,142,639,938 is 650329470.
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.
558 x 245 x 142 x 639 x 938 = 11635694877240
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
245 : 1, 5, 7, 35, 49, 245
142 : 1, 2, 71, 142
639 : 1, 3, 9, 71, 213, 639
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,245,142,639,938, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
245:5x 7x 7
142:2x 71
639:3x 3x 71
938:2x 7x 67
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 7x 71 = 17892
Therefore, the value for common factors is 17892.
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 = 11635694877240/(1x17892)
LCM = 11635694877240/17892
LCM = 650329470
Thus, we can understand that the LCM of 558,245,142,639,938 is 650329470.
