HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 675, 835, 276, 421 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 675, 835, 276, 421 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 675, 835, 276, 421 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 675, 835, 276, 421 is 1.

HCF(675, 835, 276, 421) = 1

Highest Common Factor of 675,835,276,421 using Euclid's algorithm

Highest Common Factor of 675,835,276,421 is 1

Step 1: Since 835 > 675, we apply the division lemma to 835 and 675, to get

835 = 675 x 1 + 160

Step 2: Since the reminder 675 ≠ 0, we apply division lemma to 160 and 675, to get

675 = 160 x 4 + 35

Step 3: We consider the new divisor 160 and the new remainder 35, and apply the division lemma to get

160 = 35 x 4 + 20

We consider the new divisor 35 and the new remainder 20,and apply the division lemma to get

35 = 20 x 1 + 15

We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get

20 = 15 x 1 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 675 and 835 is 5

Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(35,20) = HCF(160,35) = HCF(675,160) = HCF(835,675) .

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

Step 1: Since 276 > 5, we apply the division lemma to 276 and 5, to get

276 = 5 x 55 + 1

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 276 is 1

Notice that 1 = HCF(5,1) = HCF(276,5) .

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

Step 1: Since 421 > 1, we apply the division lemma to 421 and 1, to get

421 = 1 x 421 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 421 is 1

Notice that 1 = HCF(421,1) .
