HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 672, 943, 149, 463 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 672, 943, 149, 463 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 672, 943, 149, 463 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 672, 943, 149, 463 is 1.

HCF(672, 943, 149, 463) = 1

Highest Common Factor of 672,943,149,463 using Euclid's algorithm

Highest Common Factor of 672,943,149,463 is 1

Step 1: Since 943 > 672, we apply the division lemma to 943 and 672, to get

943 = 672 x 1 + 271

Step 2: Since the reminder 672 ≠ 0, we apply division lemma to 271 and 672, to get

672 = 271 x 2 + 130

Step 3: We consider the new divisor 271 and the new remainder 130, and apply the division lemma to get

271 = 130 x 2 + 11

We consider the new divisor 130 and the new remainder 11,and apply the division lemma to get

130 = 11 x 11 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 672 and 943 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(130,11) = HCF(271,130) = HCF(672,271) = HCF(943,672) .

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 463 > 1, we apply the division lemma to 463 and 1, to get

463 = 1 x 463 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 463 is 1

Notice that 1 = HCF(463,1) .
