HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 380, 643, 20, 896 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 380, 643, 20, 896 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 380, 643, 20, 896 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 380, 643, 20, 896 is 1.

HCF(380, 643, 20, 896) = 1

Highest common factor (HCF) of 380, 643, 20, 896 is 1.

Highest Common Factor of 380,643,20,896 using Euclid's algorithm

Highest Common Factor of 380,643,20,896 is 1

Step 1: Since 643 > 380, we apply the division lemma to 643 and 380, to get

643 = 380 x 1 + 263

Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 263 and 380, to get

380 = 263 x 1 + 117

Step 3: We consider the new divisor 263 and the new remainder 117, and apply the division lemma to get

263 = 117 x 2 + 29

We consider the new divisor 117 and the new remainder 29,and apply the division lemma to get

117 = 29 x 4 + 1

We consider the new divisor 29 and the new remainder 1,and apply the division lemma to get

29 = 1 x 29 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 380 and 643 is 1

Notice that 1 = HCF(29,1) = HCF(117,29) = HCF(263,117) = HCF(380,263) = HCF(643,380) .


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

Step 1: Since 20 > 1, we apply the division lemma to 20 and 1, to get

20 = 1 x 20 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 20 is 1

Notice that 1 = HCF(20,1) .


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

Step 1: Since 896 > 1, we apply the division lemma to 896 and 1, to get

896 = 1 x 896 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 896 is 1

Notice that 1 = HCF(896,1) .
