The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70
The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The GCF of 60, 70, and 80 is 10. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The common factors are 1, 2, 5, and 10. Therefore, the greatest common factor is 10.
The answer depends on the extent of rounding.
70/80 = 0.875 = 87.5%
70 has 8 factors; 1,2,5,7,10,14,35 and 70.
The factors of 21 are 1,3,7, and 21. The factors of 70 are 1,2,5,7,14,35, and 70 The common factors of 21 and 70 are 1 and 7.
ANSWER: 70 and 80 are not prime numbers. They are composite numbers:70 is a composite number because the factors of 70 other 1 and itself (70) are 2, 5, 7, 10, 14, and 35.80 is also a composite number because the factors of 80 other 1 and itself (80) are 2, 4, 5, 8, 10,16, 20, and 40.
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70 The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The GCF is 10.
1, 2, 5 and 10
The GCF of 60, 70, and 80 is 10. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70. The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. The common factors are 1, 2, 5, and 10. Therefore, the greatest common factor is 10.
The answer depends on the extent of rounding.
As a product of its prime factors: 2*5*7 = 70
70 + 80 + 70 + 30+ 80 + 80+ 80 = 490
let x = decrease 80- 80 x = 70 80(1-x) = 70 1-x =70/80 x = 1-70/80 = 0.125 = 12.5%
70 and 80 is 150.
80 - 70% = 80 x (1 - (70/100)) = 24
The factors of 70 are: 1, 2, 5, 7, 10, 14, 35, 70The factors of 20 are: 1, 2, 4, 5, 10, 20The common factors are: 1, 2, 5, 10
