HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 670, 434, 270 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 670, 434, 270 is 2 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, 434, 270 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, 434, 270 is 2.

HCF(670, 434, 270) = 2

Highest common factor (HCF) of 670, 434, 270 is 2.

Highest Common Factor of 670,434,270 using Euclid's algorithm

Highest Common Factor of 670,434,270 is 2

Step 1: Since 670 > 434, we apply the division lemma to 670 and 434, to get

670 = 434 x 1 + 236

Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 236 and 434, to get

434 = 236 x 1 + 198

Step 3: We consider the new divisor 236 and the new remainder 198, and apply the division lemma to get

236 = 198 x 1 + 38

We consider the new divisor 198 and the new remainder 38,and apply the division lemma to get

198 = 38 x 5 + 8

We consider the new divisor 38 and the new remainder 8,and apply the division lemma to get

38 = 8 x 4 + 6

We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get

8 = 6 x 1 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 670 and 434 is 2

Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(38,8) = HCF(198,38) = HCF(236,198) = HCF(434,236) = HCF(670,434) .


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

Step 1: Since 270 > 2, we apply the division lemma to 270 and 2, to get

270 = 2 x 135 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 270 is 2

Notice that 2 = HCF(270,2) .
