HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 177, 684, 44 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 511, 177, 684, 44 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 511, 177, 684, 44 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 511, 177, 684, 44 is 1.

HCF(511, 177, 684, 44) = 1

Highest common factor (HCF) of 511, 177, 684, 44 is 1.

Highest Common Factor of 511,177,684,44 using Euclid's algorithm

Highest Common Factor of 511,177,684,44 is 1

Step 1: Since 511 > 177, we apply the division lemma to 511 and 177, to get

511 = 177 x 2 + 157

Step 2: Since the reminder 177 ≠ 0, we apply division lemma to 157 and 177, to get

177 = 157 x 1 + 20

Step 3: We consider the new divisor 157 and the new remainder 20, and apply the division lemma to get

157 = 20 x 7 + 17

We consider the new divisor 20 and the new remainder 17,and apply the division lemma to get

20 = 17 x 1 + 3

We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get

17 = 3 x 5 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 511 and 177 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(20,17) = HCF(157,20) = HCF(177,157) = HCF(511,177) .

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

Step 1: Since 684 > 1, we apply the division lemma to 684 and 1, to get

684 = 1 x 684 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 684 is 1

Notice that 1 = HCF(684,1) .

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

Step 1: Since 44 > 1, we apply the division lemma to 44 and 1, to get

44 = 1 x 44 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 44 is 1

Notice that 1 = HCF(44,1) .
