HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 364, 625, 149 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 555, 364, 625, 149 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 555, 364, 625, 149 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 555, 364, 625, 149 is 1.

HCF(555, 364, 625, 149) = 1

Highest common factor (HCF) of 555, 364, 625, 149 is 1.

Highest Common Factor of 555,364,625,149 using Euclid's algorithm

Highest Common Factor of 555,364,625,149 is 1

Step 1: Since 555 > 364, we apply the division lemma to 555 and 364, to get

555 = 364 x 1 + 191

Step 2: Since the reminder 364 ≠ 0, we apply division lemma to 191 and 364, to get

364 = 191 x 1 + 173

Step 3: We consider the new divisor 191 and the new remainder 173, and apply the division lemma to get

191 = 173 x 1 + 18

We consider the new divisor 173 and the new remainder 18,and apply the division lemma to get

173 = 18 x 9 + 11

We consider the new divisor 18 and the new remainder 11,and apply the division lemma to get

18 = 11 x 1 + 7

We consider the new divisor 11 and the new remainder 7,and apply the division lemma to get

11 = 7 x 1 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 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 555 and 364 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(18,11) = HCF(173,18) = HCF(191,173) = HCF(364,191) = HCF(555,364) .


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

Step 1: Since 625 > 1, we apply the division lemma to 625 and 1, to get

625 = 1 x 625 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 625 is 1

Notice that 1 = HCF(625,1) .


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) .
