Find LCM of 974,696,551,152,661 with Prime Factorization
| 2 | 974, 696, 551, 152, 661 |
| 2 | 487, 348, 551, 76, 661 |
| 2 | 487, 174, 551, 38, 661 |
| 19 | 487, 87, 551, 19, 661 |
| 29 | 487, 87, 29, 1, 661 |
| 487, 3, 1, 1, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 29 x 487 x 3 x 1 x 1 x 661 = 4256898168
Therefore, the lowest common multiple of 974,696,551,152,661 is 4256898168.
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.
974 x 696 x 551 x 152 x 661 = 37528814249088
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.
974 : 1, 2, 487, 974
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
551 : 1, 19, 29, 551
152 : 1, 2, 4, 8, 19, 38, 76, 152
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,696,551,152,661, is 1.
Now, the common factors can be found like this.
974:2x 487
696:2x 2x 2x 3x 29
551:19x 29
152:2x 2x 2x 19
661:661
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 2x 19x 29 = 8816
Therefore, the value for common factors is 8816.
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 = 37528814249088/(1x8816)
LCM = 37528814249088/8816
LCM = 4256898168
Thus, we can understand that the LCM of 974,696,551,152,661 is 4256898168.
