HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 304, 775, 19 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 304, 775, 19 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 304, 775, 19 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 304, 775, 19 is 1.

HCF(304, 775, 19) = 1

Highest common factor (HCF) of 304, 775, 19 is 1.

Highest Common Factor of 304,775,19 using Euclid's algorithm

Highest Common Factor of 304,775,19 is 1

Step 1: Since 775 > 304, we apply the division lemma to 775 and 304, to get

775 = 304 x 2 + 167

Step 2: Since the reminder 304 ≠ 0, we apply division lemma to 167 and 304, to get

304 = 167 x 1 + 137

Step 3: We consider the new divisor 167 and the new remainder 137, and apply the division lemma to get

167 = 137 x 1 + 30

We consider the new divisor 137 and the new remainder 30,and apply the division lemma to get

137 = 30 x 4 + 17

We consider the new divisor 30 and the new remainder 17,and apply the division lemma to get

30 = 17 x 1 + 13

We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get

17 = 13 x 1 + 4

We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get

13 = 4 x 3 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 304 and 775 is 1

Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(30,17) = HCF(137,30) = HCF(167,137) = HCF(304,167) = HCF(775,304) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 19 > 1, we apply the division lemma to 19 and 1, to get

19 = 1 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 19 is 1

Notice that 1 = HCF(19,1) .
