Find LCM of 620,918,987,191,700 with Prime Factorization
| 2 | 620, 918, 987, 191, 700 |
| 2 | 310, 459, 987, 191, 350 |
| 3 | 155, 459, 987, 191, 175 |
| 5 | 155, 153, 329, 191, 175 |
| 7 | 31, 153, 329, 191, 35 |
| 31, 153, 47, 191, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 31 x 153 x 47 x 191 x 5 = 89413613100
Therefore, the lowest common multiple of 620,918,987,191,700 is 89413613100.
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.
620 x 918 x 987 x 191 x 700 = 75107435004000
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
987 : 1, 3, 7, 21, 47, 141, 329, 987
191 : 1, 191
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,918,987,191,700, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
918:2x 3x 3x 3x 17
987:3x 7x 47
191:191
700:2x 2x 5x 5x 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 7 = 840
Therefore, the value for common factors is 840.
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 = 75107435004000/(1x840)
LCM = 75107435004000/840
LCM = 89413613100
Thus, we can understand that the LCM of 620,918,987,191,700 is 89413613100.
