53 is a prime number because it has exactly two factors, 1 and the number itself. 35, 27, and 49 are composite numbers because they have more than two factors.
The greatest common divisor of the numbers 35 and 49 is 7.
It is: 35/49 = 5/7
The greatest common factor of 35, 49, and 84 is 7. The GCF of 35, 49, and 84 is 7. The prime factorization of 35 is 5*7. The prime factorization of 49 is 7*7 The prime factorization of 84 is 2*2*3*7 The GCF of 35, 49, and 84 is thus 7.
The GCF of 21, 35, and 49 is 7.The GCF is 7.Factors of 21: 1, 3, 7, 21Factors of 35: 1, 5, 7, 35Factors of 49: 1, 7, 49GCF (21, 35, 49) = 7
So, 49 is .35 of the original number. That means 49 is 35/100ths of the original number. Divide 49 by 35- that gets you 1/100th of the original number. Take THAT number, multiply by 100, and you have the original number.
14 and 35 make 49.
35/100 x 140 = 49
35/100 x 140 = 49
49 ÷ 5 = 9 with remainder 4

1 and 7.
The only number is 7. 7x5=35 7x7=49
The divisors of 735 are 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, and 735.
Please think a little with me-- What are the factors of 49 ? Do you know what the word factor means? It is another word for divisor-- so what number divides exactly into 49? Think through the multiplication table-- does 49 ever appear??? Yes! 49= 7 times 7. Now think about 35-- it that number in your multiplication table? What the factors of 35? HInt: any number that ends in 0 or 5 has 5 for a factor. So finally, if you have not already figured it out: 35 = 5 times 7. So the factors are 7 and 7 for 49 and 7 and 5 for 35. "common" means "in common" - a factor they both share-- What factor do these number have in common??
42, 49, 56, 63, 70.....
-49 - 35 = -84
