Find LCM of 658,139,420,575,252 with Prime Factorization
2 | 658, 139, 420, 575, 252 |
2 | 329, 139, 210, 575, 126 |
3 | 329, 139, 105, 575, 63 |
5 | 329, 139, 35, 575, 21 |
7 | 329, 139, 7, 115, 21 |
47, 139, 1, 115, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 47 x 139 x 1 x 115 x 3 = 946631700
Therefore, the lowest common multiple of 658,139,420,575,252 is 946631700.
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.
658 x 139 x 420 x 575 x 252 = 5566194396000
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
139 : 1, 139
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
575 : 1, 5, 23, 25, 115, 575
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,139,420,575,252, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
139:139
420:2x 2x 3x 5x 7
575:5x 5x 23
252:2x 2x 3x 3x 7
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 5x 7x 7 = 5880
Therefore, the value for common factors is 5880.
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 = 5566194396000/(1x5880)
LCM = 5566194396000/5880
LCM = 946631700
Thus, we can understand that the LCM of 658,139,420,575,252 is 946631700.
