HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 149, 853, 302 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 149, 853, 302 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 149, 853, 302 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 149, 853, 302 is 1.

HCF(149, 853, 302) = 1

Highest common factor (HCF) of 149, 853, 302 is 1.

Highest Common Factor of 149,853,302 using Euclid's algorithm

Highest Common Factor of 149,853,302 is 1

Step 1: Since 853 > 149, we apply the division lemma to 853 and 149, to get

853 = 149 x 5 + 108

Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 108 and 149, to get

149 = 108 x 1 + 41

Step 3: We consider the new divisor 108 and the new remainder 41, and apply the division lemma to get

108 = 41 x 2 + 26

We consider the new divisor 41 and the new remainder 26,and apply the division lemma to get

41 = 26 x 1 + 15

We consider the new divisor 26 and the new remainder 15,and apply the division lemma to get

26 = 15 x 1 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 149 and 853 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(26,15) = HCF(41,26) = HCF(108,41) = HCF(149,108) = HCF(853,149) .

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

Step 1: Since 302 > 1, we apply the division lemma to 302 and 1, to get

302 = 1 x 302 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 302 is 1

Notice that 1 = HCF(302,1) .
