HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 797, 548 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 438, 797, 548 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 438, 797, 548 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 438, 797, 548 is 1.

HCF(438, 797, 548) = 1

Highest common factor (HCF) of 438, 797, 548 is 1.

Highest Common Factor of 438,797,548 using Euclid's algorithm

Highest Common Factor of 438,797,548 is 1

Step 1: Since 797 > 438, we apply the division lemma to 797 and 438, to get

797 = 438 x 1 + 359

Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 359 and 438, to get

438 = 359 x 1 + 79

Step 3: We consider the new divisor 359 and the new remainder 79, and apply the division lemma to get

359 = 79 x 4 + 43

We consider the new divisor 79 and the new remainder 43,and apply the division lemma to get

79 = 43 x 1 + 36

We consider the new divisor 43 and the new remainder 36,and apply the division lemma to get

43 = 36 x 1 + 7

We consider the new divisor 36 and the new remainder 7,and apply the division lemma to get

36 = 7 x 5 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 438 and 797 is 1

Notice that 1 = HCF(7,1) = HCF(36,7) = HCF(43,36) = HCF(79,43) = HCF(359,79) = HCF(438,359) = HCF(797,438) .

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

Step 1: Since 548 > 1, we apply the division lemma to 548 and 1, to get

548 = 1 x 548 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 548 is 1

Notice that 1 = HCF(548,1) .
