5 x 7 x 11 = 385
275 = 5 x 5 x 11 385 = 5 x 7 x 11 Cross out the ones in common. 275/385 = 5/7
As a product of its prime factors: 3*5*5*5 = 375
Prime factors of 210 are: 2, 3, 5 and 7 Prime factors of 385 are: 5,7 and 11 Common factors are: 5 and 7 and so 5*7 = 35 which is the hcf
A prime number has only 2 factors: 1 and itself. 385 has a 5 in the ones place, so 5 is also a factor. Since 5 X 77 = 385, 77 is a factor, too. There might be other factors. 385 is a composite number because it has more factors than 1 and itself.
5 x 7 x 11 = 385
5 x 7 x 11 = 385
The prime factors are: 5, 7 and 11 (5x7x11 = 385)
As a product of its prime factors: 5*7*11 = 385
As a product of its prime factors: 5*7*11 = 385
5 times 7 times 11 equals 385
275 = 5 x 5 x 11 385 = 5 x 7 x 11 Cross out the ones in common. 275/385 = 5/7
