The LCM of 658,430,865,987,202 is 7415715930.
Find LCM of 658,430,865,987,202 with Prime Factorization
| 2 | 658, 430, 865, 987, 202 |
| 5 | 329, 215, 865, 987, 101 |
| 7 | 329, 43, 173, 987, 101 |
| 47 | 47, 43, 173, 141, 101 |
| 1, 43, 173, 3, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 47 x 1 x 43 x 173 x 3 x 101 = 7415715930
Therefore, the lowest common multiple of 658,430,865,987,202 is 7415715930.
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 430 x 865 x 987 x 202 = 48795410819400
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
430 : 1, 2, 5, 10, 43, 86, 215, 430
865 : 1, 5, 173, 865
987 : 1, 3, 7, 21, 47, 141, 329, 987
202 : 1, 2, 101, 202
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,430,865,987,202, is 1.
Now, the common factors can be found like this.
658:2x 7x 47
430:2x 5x 43
865:5x 173
987:3x 7x 47
202:2x 101
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 5x 7x 47 = 6580
Therefore, the value for common factors is 6580.
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 = 48795410819400/(1x6580)
LCM = 48795410819400/6580
LCM = 7415715930
Thus, we can understand that the LCM of 658,430,865,987,202 is 7415715930.
