135 = 5 x 27 = 33 x 5 I always divide by 5 first for all numbers that end in 0 or 5, and I divide by 2 first for all other even numbers.
It is: 2*5*5 = 50 or as 2*52 = 50
30 + 40 = 70 5 * 14 = 70
It is: 2*5*7 = 70
To find numbers that are multiples of both 3 and 5, we need to find the numbers that are common multiples of both 3 and 5. These are numbers that are divisible by the least common multiple of 3 and 5, which is 15. The first four numbers less than 70 that are multiples of both 3 and 5 are 15, 30, 45, and 60.
135 = 5 x 27 = 33 x 5 I always divide by 5 first for all numbers that end in 0 or 5, and I divide by 2 first for all other even numbers.
It is: 2*5*5 = 50 or as 2*52 = 50
30 + 40 = 70 5 * 14 = 70
70 = 2 * 5 * 7.
The greatest common factor? Start by factoring both numbers into primes: 25 = 5*5 70 = 2*5*7 The only prime factor in common is a single 5. So the answer is 5.
It is: 2*5*7 = 70
It is: 2*5*7 = 70
70 written as a product of prime numbers: 2 x 5 x 7
70 = 2 x 5 x 7
As a product of its prime factors: 2*5*7 = 70
2 x 5 x 7 = 70
1, 2, 5, 7, 10, 14, 35, 70
