Find LCM of 641,253,594,426,620 with Prime Factorization
2 | 641, 253, 594, 426, 620 |
3 | 641, 253, 297, 213, 310 |
11 | 641, 253, 99, 71, 310 |
641, 23, 9, 71, 310 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 641 x 23 x 9 x 71 x 310 = 192749097420
Therefore, the lowest common multiple of 641,253,594,426,620 is 192749097420.
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.
641 x 253 x 594 x 426 x 620 = 25442880859440
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.
641 : 1, 641
253 : 1, 11, 23, 253
594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594
426 : 1, 2, 3, 6, 71, 142, 213, 426
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,253,594,426,620, is 1.
Now, the common factors can be found like this.
641:641
253:11x 23
594:2x 3x 3x 3x 11
426:2x 3x 71
620:2x 2x 5x 31
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 11 = 132
Therefore, the value for common factors is 132.
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 = 25442880859440/(1x132)
LCM = 25442880859440/132
LCM = 192749097420
Thus, we can understand that the LCM of 641,253,594,426,620 is 192749097420.
