HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 542, 473 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 785, 542, 473 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 785, 542, 473 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 785, 542, 473 is 1.

HCF(785, 542, 473) = 1

Highest common factor (HCF) of 785, 542, 473 is 1.

Highest Common Factor of 785,542,473 using Euclid's algorithm

Highest Common Factor of 785,542,473 is 1

Step 1: Since 785 > 542, we apply the division lemma to 785 and 542, to get

785 = 542 x 1 + 243

Step 2: Since the reminder 542 ≠ 0, we apply division lemma to 243 and 542, to get

542 = 243 x 2 + 56

Step 3: We consider the new divisor 243 and the new remainder 56, and apply the division lemma to get

243 = 56 x 4 + 19

We consider the new divisor 56 and the new remainder 19,and apply the division lemma to get

56 = 19 x 2 + 18

We consider the new divisor 19 and the new remainder 18,and apply the division lemma to get

19 = 18 x 1 + 1

We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get

18 = 1 x 18 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 785 and 542 is 1

Notice that 1 = HCF(18,1) = HCF(19,18) = HCF(56,19) = HCF(243,56) = HCF(542,243) = HCF(785,542) .

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

Step 1: Since 473 > 1, we apply the division lemma to 473 and 1, to get

473 = 1 x 473 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 473 is 1

Notice that 1 = HCF(473,1) .
