Find LCM of 670,134,820,285,992 with Prime Factorization


2 670, 134, 820, 285, 992
2 335, 67, 410, 285, 496
5 335, 67, 205, 285, 248
67 67, 67, 41, 57, 248
1, 1, 41, 57, 248

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 5 x 67 x 1 x 1 x 41 x 57 x 248 = 776631840

Therefore, the lowest common multiple of 670,134,820,285,992 is 776631840.

LCM Formula to Find Lowest Common Multiple of 670,134,820,285,992

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.

670 x 134 x 820 x 285 x 992 = 20813733312000

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

134 : 1, 2, 67, 134

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

285 : 1, 3, 5, 15, 19, 57, 95, 285

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,134,820,285,992, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

134:2x 67

820:2x 2x 5x 41

285:3x 5x 19

992:2x 2x 2x 2x 2x 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 2x 2x 5x 5x 67 = 26800

Therefore, the value for common factors is 26800.

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 = 20813733312000/(1x26800)

LCM = 20813733312000/26800

LCM = 776631840

Thus, we can understand that the LCM of 670,134,820,285,992 is 776631840.
