HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 497, 930 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 670, 497, 930 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 670, 497, 930 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 670, 497, 930 is 1.

HCF(670, 497, 930) = 1

Highest common factor (HCF) of 670, 497, 930 is 1.

Highest Common Factor of 670,497,930 using Euclid's algorithm

Highest Common Factor of 670,497,930 is 1

Step 1: Since 670 > 497, we apply the division lemma to 670 and 497, to get

670 = 497 x 1 + 173

Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 173 and 497, to get

497 = 173 x 2 + 151

Step 3: We consider the new divisor 173 and the new remainder 151, and apply the division lemma to get

173 = 151 x 1 + 22

We consider the new divisor 151 and the new remainder 22,and apply the division lemma to get

151 = 22 x 6 + 19

We consider the new divisor 22 and the new remainder 19,and apply the division lemma to get

22 = 19 x 1 + 3

We consider the new divisor 19 and the new remainder 3,and apply the division lemma to get

19 = 3 x 6 + 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 670 and 497 is 1

Notice that 1 = HCF(3,1) = HCF(19,3) = HCF(22,19) = HCF(151,22) = HCF(173,151) = HCF(497,173) = HCF(670,497) .

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

Step 1: Since 930 > 1, we apply the division lemma to 930 and 1, to get

930 = 1 x 930 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 930 is 1

Notice that 1 = HCF(930,1) .
