HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 430, 207 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 670, 430, 207 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, 430, 207 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, 430, 207 is 1.

HCF(670, 430, 207) = 1

Highest Common Factor of 670,430,207 using Euclid's algorithm

Highest Common Factor of 670,430,207 is 1

Step 1: Since 670 > 430, we apply the division lemma to 670 and 430, to get

670 = 430 x 1 + 240

Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 240 and 430, to get

430 = 240 x 1 + 190

Step 3: We consider the new divisor 240 and the new remainder 190, and apply the division lemma to get

240 = 190 x 1 + 50

We consider the new divisor 190 and the new remainder 50,and apply the division lemma to get

190 = 50 x 3 + 40

We consider the new divisor 50 and the new remainder 40,and apply the division lemma to get

50 = 40 x 1 + 10

We consider the new divisor 40 and the new remainder 10,and apply the division lemma to get

40 = 10 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 670 and 430 is 10

Notice that 10 = HCF(40,10) = HCF(50,40) = HCF(190,50) = HCF(240,190) = HCF(430,240) = HCF(670,430) .

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

Step 1: Since 207 > 10, we apply the division lemma to 207 and 10, to get

207 = 10 x 20 + 7

Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 7 and 10, to get

10 = 7 x 1 + 3

Step 3: We consider the new divisor 7 and the new remainder 3, and apply the division lemma to get

7 = 3 x 2 + 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 10 and 207 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(207,10) .
