HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 912, 775, 520 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 912, 775, 520 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 912, 775, 520 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 912, 775, 520 is 1.

HCF(912, 775, 520) = 1

Highest common factor (HCF) of 912, 775, 520 is 1.

Highest Common Factor of 912,775,520 using Euclid's algorithm

Highest Common Factor of 912,775,520 is 1

Step 1: Since 912 > 775, we apply the division lemma to 912 and 775, to get

912 = 775 x 1 + 137

Step 2: Since the reminder 775 ≠ 0, we apply division lemma to 137 and 775, to get

775 = 137 x 5 + 90

Step 3: We consider the new divisor 137 and the new remainder 90, and apply the division lemma to get

137 = 90 x 1 + 47

We consider the new divisor 90 and the new remainder 47,and apply the division lemma to get

90 = 47 x 1 + 43

We consider the new divisor 47 and the new remainder 43,and apply the division lemma to get

47 = 43 x 1 + 4

We consider the new divisor 43 and the new remainder 4,and apply the division lemma to get

43 = 4 x 10 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 912 and 775 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(43,4) = HCF(47,43) = HCF(90,47) = HCF(137,90) = HCF(775,137) = HCF(912,775) .

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

Step 1: Since 520 > 1, we apply the division lemma to 520 and 1, to get

520 = 1 x 520 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 520 is 1

Notice that 1 = HCF(520,1) .
