HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 613, 253, 149, 285 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 613, 253, 149, 285 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 613, 253, 149, 285 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 613, 253, 149, 285 is 1.

HCF(613, 253, 149, 285) = 1

Highest Common Factor of 613,253,149,285 using Euclid's algorithm

Highest Common Factor of 613,253,149,285 is 1

Step 1: Since 613 > 253, we apply the division lemma to 613 and 253, to get

613 = 253 x 2 + 107

Step 2: Since the reminder 253 ≠ 0, we apply division lemma to 107 and 253, to get

253 = 107 x 2 + 39

Step 3: We consider the new divisor 107 and the new remainder 39, and apply the division lemma to get

107 = 39 x 2 + 29

We consider the new divisor 39 and the new remainder 29,and apply the division lemma to get

39 = 29 x 1 + 10

We consider the new divisor 29 and the new remainder 10,and apply the division lemma to get

29 = 10 x 2 + 9

We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get

10 = 9 x 1 + 1

We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get

9 = 1 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 613 and 253 is 1

Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(29,10) = HCF(39,29) = HCF(107,39) = HCF(253,107) = HCF(613,253) .

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

Step 1: Since 149 > 1, we apply the division lemma to 149 and 1, to get

149 = 1 x 149 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 149 is 1

Notice that 1 = HCF(149,1) .

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

Step 1: Since 285 > 1, we apply the division lemma to 285 and 1, to get

285 = 1 x 285 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 285 is 1

Notice that 1 = HCF(285,1) .
