HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 155, 48, 651, 515 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 155, 48, 651, 515 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 155, 48, 651, 515 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 155, 48, 651, 515 is 1.

HCF(155, 48, 651, 515) = 1

Highest common factor (HCF) of 155, 48, 651, 515 is 1.

Highest Common Factor of 155,48,651,515 using Euclid's algorithm

Highest Common Factor of 155,48,651,515 is 1

Step 1: Since 155 > 48, we apply the division lemma to 155 and 48, to get

155 = 48 x 3 + 11

Step 2: Since the reminder 48 ≠ 0, we apply division lemma to 11 and 48, to get

48 = 11 x 4 + 4

Step 3: 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 155 and 48 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(48,11) = HCF(155,48) .


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

Step 1: Since 651 > 1, we apply the division lemma to 651 and 1, to get

651 = 1 x 651 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 651 is 1

Notice that 1 = HCF(651,1) .


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

Step 1: Since 515 > 1, we apply the division lemma to 515 and 1, to get

515 = 1 x 515 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 515 is 1

Notice that 1 = HCF(515,1) .
