HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 375, 636, 505 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 375, 636, 505 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 375, 636, 505 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 375, 636, 505 is 1.

HCF(375, 636, 505) = 1

Highest Common Factor of 375,636,505 using Euclid's algorithm

Highest Common Factor of 375,636,505 is 1

Step 1: Since 636 > 375, we apply the division lemma to 636 and 375, to get

636 = 375 x 1 + 261

Step 2: Since the reminder 375 ≠ 0, we apply division lemma to 261 and 375, to get

375 = 261 x 1 + 114

Step 3: We consider the new divisor 261 and the new remainder 114, and apply the division lemma to get

261 = 114 x 2 + 33

We consider the new divisor 114 and the new remainder 33,and apply the division lemma to get

114 = 33 x 3 + 15

We consider the new divisor 33 and the new remainder 15,and apply the division lemma to get

33 = 15 x 2 + 3

We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get

15 = 3 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 375 and 636 is 3

Notice that 3 = HCF(15,3) = HCF(33,15) = HCF(114,33) = HCF(261,114) = HCF(375,261) = HCF(636,375) .

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

Step 1: Since 505 > 3, we apply the division lemma to 505 and 3, to get

505 = 3 x 168 + 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 505 is 1

Notice that 1 = HCF(3,1) = HCF(505,3) .
