HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 555, 912, 238 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 555, 912, 238 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, 912, 238 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, 912, 238 is 1.

HCF(555, 912, 238) = 1

Highest common factor (HCF) of 555, 912, 238 is 1.

Highest Common Factor of 555,912,238 using Euclid's algorithm

Highest Common Factor of 555,912,238 is 1

Step 1: Since 912 > 555, we apply the division lemma to 912 and 555, to get

912 = 555 x 1 + 357

Step 2: Since the reminder 555 ≠ 0, we apply division lemma to 357 and 555, to get

555 = 357 x 1 + 198

Step 3: We consider the new divisor 357 and the new remainder 198, and apply the division lemma to get

357 = 198 x 1 + 159

We consider the new divisor 198 and the new remainder 159,and apply the division lemma to get

198 = 159 x 1 + 39

We consider the new divisor 159 and the new remainder 39,and apply the division lemma to get

159 = 39 x 4 + 3

We consider the new divisor 39 and the new remainder 3,and apply the division lemma to get

39 = 3 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 555 and 912 is 3

Notice that 3 = HCF(39,3) = HCF(159,39) = HCF(198,159) = HCF(357,198) = HCF(555,357) = HCF(912,555) .

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

Step 1: Since 238 > 3, we apply the division lemma to 238 and 3, to get

238 = 3 x 79 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 238 is 1

Notice that 1 = HCF(3,1) = HCF(238,3) .
