HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 664, 846, 151 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 664, 846, 151 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 664, 846, 151 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 664, 846, 151 is 1.

HCF(664, 846, 151) = 1

Highest common factor (HCF) of 664, 846, 151 is 1.

Highest Common Factor of 664,846,151 using Euclid's algorithm

Highest Common Factor of 664,846,151 is 1

Step 1: Since 846 > 664, we apply the division lemma to 846 and 664, to get

846 = 664 x 1 + 182

Step 2: Since the reminder 664 ≠ 0, we apply division lemma to 182 and 664, to get

664 = 182 x 3 + 118

Step 3: We consider the new divisor 182 and the new remainder 118, and apply the division lemma to get

182 = 118 x 1 + 64

We consider the new divisor 118 and the new remainder 64,and apply the division lemma to get

118 = 64 x 1 + 54

We consider the new divisor 64 and the new remainder 54,and apply the division lemma to get

64 = 54 x 1 + 10

We consider the new divisor 54 and the new remainder 10,and apply the division lemma to get

54 = 10 x 5 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 664 and 846 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(54,10) = HCF(64,54) = HCF(118,64) = HCF(182,118) = HCF(664,182) = HCF(846,664) .

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

Step 1: Since 151 > 2, we apply the division lemma to 151 and 2, to get

151 = 2 x 75 + 1

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

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 151 is 1

Notice that 1 = HCF(2,1) = HCF(151,2) .
