2x5x7
Prime factors of 60 are: 2, 3 and 5 Prime factors of 70 are: 2, 5 and 7
One way to solve this is to multiply the lowest prime numbers together, starting from 2: 2x3=6. 6x5=30. Multiplying by 7 would yield a 3-digit number, so we are looking for all 2-digit numbers with 3 distinct prime factors. We already have 30. 2x3x7=42. 2x3x11=66. 2x3x13=78. 2x5x7=70. So, to answer the original question, the 2-digit numbers that have the most factors in their prime factorization are, in ascending order, 30, 42, 66, 70, and 78.
154/2=77, 154/7=22; 154/11=14; 2x7x11=154 70/2=35, 70/5=14; 70/7=10; 2x5x7=70 182/2=91; 154/7=13; 2x7x13=182 The only common prime factors are 2 and 7; 7 is the largest of the prime factors and 14 is the largest common divisor of all three numbers.
The prime factors of 70 are 2,5 and 7 so their product is 70. This will happen whenever the prime factors occur only once. When we factor 70 into primes, we are asking for those primes who product is equal to 70. However, sometimes we get one or more primes raise to a power in the prime factorization. In this case, the prime raised to a power is no longer a prime so the product of prime factors is less than the number.
No. The prime factors of 140 are 2,2,5 and 7 The prime factors of 210 are 2,3,5 and 7 The common prime factors are 2,5 and 7 Thus the HCF is 2x5x7, or 70.
Prime factor each one. 70= 2x5x7 198=2x3x3x11 Multiply the common factors that appear the most it appears in either number. 2x3x3x5x7x11=6930
In order to find the factors of a number you first have to break it down into its prime factors. In this case, 70 can be broken down as follows: 70 = 2x5x7 To find other factors (apart from 1) you need to multiply any combination of these prime factors together. Doing this gives us the factors of 70 as: 1, 2, 5, 7, 10, 14, 35 and 70.
Method of prime factorization is one of the best methods to find L.C.M. Prime factorization of 81 = 3x3x3x3 Prime factorization of 70 = 2x5x7 It is clear that nothing is common in Prime Factorization of both numbers. Also, L.C.M. = Product of common numbers x Product of uncommon factors So, L.C.M. of 81 and 70 = Product of 81 and 70(Because nothing is common in 71 and 80) = 81 x 70 = 5670
To find the GCF of two numbers, you must first express them as their prime factors. In this case, that would be: 85 = 5x17 70 = 2x5x7 The next step would be to identify any common factors. In this case the only common factor is 5. Thus, the GCF of 85 and 70 is 5.
The prime factors of 18 are 2, 3, and 3. The prime factors of 70 are 2, 5, and 7. The prime factors that 18 and 70 have in common are a single 2.
Three:The Prime Factors of 70 are 2, 5, 7.
2x5x7
The distinct prime factors of 70 are 2, 5, and 7, so it has three distinct prime factors.
