HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 905, 763 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 542, 905, 763 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 542, 905, 763 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 542, 905, 763 is 1.

HCF(542, 905, 763) = 1

HCF of 542, 905, 763 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 542, 905, 763 is 1.

Highest Common Factor of 542,905,763 using Euclid's algorithm

Highest Common Factor of 542,905,763 is 1

Step 1: Since 905 > 542, we apply the division lemma to 905 and 542, to get

905 = 542 x 1 + 363

Step 2: Since the reminder 542 ≠ 0, we apply division lemma to 363 and 542, to get

542 = 363 x 1 + 179

Step 3: We consider the new divisor 363 and the new remainder 179, and apply the division lemma to get

363 = 179 x 2 + 5

We consider the new divisor 179 and the new remainder 5,and apply the division lemma to get

179 = 5 x 35 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 542 and 905 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(179,5) = HCF(363,179) = HCF(542,363) = HCF(905,542) .

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

Step 1: Since 763 > 1, we apply the division lemma to 763 and 1, to get

763 = 1 x 763 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 763 is 1

Notice that 1 = HCF(763,1) .
