To find the greatest common factor (GCF) of 36, 60, and 84, you can break down each number into its prime factorization and then identify the common prime factors. Prime factorization of 36: 36 = 2 2 × 3 2 36=2 2 ×3 2 Prime factorization of 60: 60 = 2 2 × 3 × 5 60=2 2 ×3×5 Prime factorization of 84: 84 = 2 2 × 3 × 7 84=2 2 ×3×7 Now, identify the common prime factors and multiply them: � � � ( 36 , 60 , 84 ) = 2 2 × 3 = 12 GCF(36,60,84)=2 2 ×3=12 So, the greatest common factor of 36, 60, and 84 is 12.
2 and 3
The common factors of 60 and 84 are: 1, 2, 3, 4, 6, and 12
It is: 12
The prime factors of 84 are: 2,3,7The prime factors of 360 are: 2,3,5
The LCM of 60 and 84 is 420. the prime factors of 60 are 2,2,3,5 the prime factors of 84 are 2,2,3,7 combining them all together to use all the factors = 2,2,3,5,7 = 420 Take the greatest QUANTITY of each number. so we have 2 - 2's , 1 - 3 , 1 - 5 , and 1 - 7. 2 x 2 x 3 x 5 x 7 = 420
The prime factors of 84 are: 2, 3 and 7.
The prime factors are: 2,3,7They are: 2, 3 and 7The prime factors of 84 are: 2,3,7The prime factors of 84 are: 2,3,7
To determine the least common multiple of two numbers, determine the prime factors of both number. Then, determine the prime factors they have in common. Multiply all their prime factors together (in other words, multiply both numbers together) and divide by the prime factors they have in common (in other words, their greatest common factor). The prime factors of 21 are 3 and 7. The prime factors of 28 are 2, 2, and 7. The prime factors in common are a single 7. Therefore, the lowest common multiple is 21 x 28 ÷ 7 = 84
The prime factors of 84 are 2x2x3x7.
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 16 are 1, 2, 4, 8, and 16. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 84 are 2, 2, 3, and 7. The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 = 4.
By prime factoring 84 you get 2x2x7x3. These are all the factors of 84
