HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 618, 380 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 505, 618, 380 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 505, 618, 380 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 505, 618, 380 is 1.

HCF(505, 618, 380) = 1

HCF of 505, 618, 380 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 505, 618, 380 is 1.

Highest Common Factor of 505,618,380 using Euclid's algorithm

Highest Common Factor of 505,618,380 is 1

Step 1: Since 618 > 505, we apply the division lemma to 618 and 505, to get

618 = 505 x 1 + 113

Step 2: Since the reminder 505 ≠ 0, we apply division lemma to 113 and 505, to get

505 = 113 x 4 + 53

Step 3: We consider the new divisor 113 and the new remainder 53, and apply the division lemma to get

113 = 53 x 2 + 7

We consider the new divisor 53 and the new remainder 7,and apply the division lemma to get

53 = 7 x 7 + 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 505 and 618 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(53,7) = HCF(113,53) = HCF(505,113) = HCF(618,505) .

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

Step 1: Since 380 > 1, we apply the division lemma to 380 and 1, to get

380 = 1 x 380 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 380 is 1

Notice that 1 = HCF(380,1) .
