HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 815 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 542, 815 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, 815 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, 815 is 1.

HCF(542, 815) = 1

HCF of 542, 815 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, 815 is 1.

Highest Common Factor of 542,815 using Euclid's algorithm

Highest Common Factor of 542,815 is 1

Step 1: Since 815 > 542, we apply the division lemma to 815 and 542, to get

815 = 542 x 1 + 273

Step 2: Since the reminder 542 ≠ 0, we apply division lemma to 273 and 542, to get

542 = 273 x 1 + 269

Step 3: We consider the new divisor 273 and the new remainder 269, and apply the division lemma to get

273 = 269 x 1 + 4

We consider the new divisor 269 and the new remainder 4,and apply the division lemma to get

269 = 4 x 67 + 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 815 is 1

Notice that 1 = HCF(4,1) = HCF(269,4) = HCF(273,269) = HCF(542,273) = HCF(815,542) .
