HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 994, 1209, 4920 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 994, 1209, 4920 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 994, 1209, 4920 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 994, 1209, 4920 is 1.

HCF(994, 1209, 4920) = 1

Highest common factor (HCF) of 994, 1209, 4920 is 1.

Highest Common Factor of 994,1209,4920 using Euclid's algorithm

Highest Common Factor of 994,1209,4920 is 1

Step 1: Since 1209 > 994, we apply the division lemma to 1209 and 994, to get

1209 = 994 x 1 + 215

Step 2: Since the reminder 994 ≠ 0, we apply division lemma to 215 and 994, to get

994 = 215 x 4 + 134

Step 3: We consider the new divisor 215 and the new remainder 134, and apply the division lemma to get

215 = 134 x 1 + 81

We consider the new divisor 134 and the new remainder 81,and apply the division lemma to get

134 = 81 x 1 + 53

We consider the new divisor 81 and the new remainder 53,and apply the division lemma to get

81 = 53 x 1 + 28

We consider the new divisor 53 and the new remainder 28,and apply the division lemma to get

53 = 28 x 1 + 25

We consider the new divisor 28 and the new remainder 25,and apply the division lemma to get

28 = 25 x 1 + 3

We consider the new divisor 25 and the new remainder 3,and apply the division lemma to get

25 = 3 x 8 + 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 994 and 1209 is 1

Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(28,25) = HCF(53,28) = HCF(81,53) = HCF(134,81) = HCF(215,134) = HCF(994,215) = HCF(1209,994) .

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

Step 1: Since 4920 > 1, we apply the division lemma to 4920 and 1, to get

4920 = 1 x 4920 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4920 is 1

Notice that 1 = HCF(4920,1) .
