HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 538, 386, 819, 946 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 538, 386, 819, 946 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 538, 386, 819, 946 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 538, 386, 819, 946 is 1.

HCF(538, 386, 819, 946) = 1

Highest common factor (HCF) of 538, 386, 819, 946 is 1.

Highest Common Factor of 538,386,819,946 using Euclid's algorithm

Highest Common Factor of 538,386,819,946 is 1

Step 1: Since 538 > 386, we apply the division lemma to 538 and 386, to get

538 = 386 x 1 + 152

Step 2: Since the reminder 386 ≠ 0, we apply division lemma to 152 and 386, to get

386 = 152 x 2 + 82

Step 3: We consider the new divisor 152 and the new remainder 82, and apply the division lemma to get

152 = 82 x 1 + 70

We consider the new divisor 82 and the new remainder 70,and apply the division lemma to get

82 = 70 x 1 + 12

We consider the new divisor 70 and the new remainder 12,and apply the division lemma to get

70 = 12 x 5 + 10

We consider the new divisor 12 and the new remainder 10,and apply the division lemma to get

12 = 10 x 1 + 2

We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get

10 = 2 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 538 and 386 is 2

Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(70,12) = HCF(82,70) = HCF(152,82) = HCF(386,152) = HCF(538,386) .


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

Step 1: Since 819 > 2, we apply the division lemma to 819 and 2, to get

819 = 2 x 409 + 1

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

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 819 is 1

Notice that 1 = HCF(2,1) = HCF(819,2) .


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

Step 1: Since 946 > 1, we apply the division lemma to 946 and 1, to get

946 = 1 x 946 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 946 is 1

Notice that 1 = HCF(946,1) .
