HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 217, 442 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 947, 217, 442 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 947, 217, 442 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 947, 217, 442 is 1.

HCF(947, 217, 442) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 947, 217, 442 is 1.

Highest Common Factor of 947,217,442 using Euclid's algorithm

Highest Common Factor of 947,217,442 is 1

Step 1: Since 947 > 217, we apply the division lemma to 947 and 217, to get

947 = 217 x 4 + 79

Step 2: Since the reminder 217 ≠ 0, we apply division lemma to 79 and 217, to get

217 = 79 x 2 + 59

Step 3: We consider the new divisor 79 and the new remainder 59, and apply the division lemma to get

79 = 59 x 1 + 20

We consider the new divisor 59 and the new remainder 20,and apply the division lemma to get

59 = 20 x 2 + 19

We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get

20 = 19 x 1 + 1

We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get

19 = 1 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 947 and 217 is 1

Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(59,20) = HCF(79,59) = HCF(217,79) = HCF(947,217) .

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

Step 1: Since 442 > 1, we apply the division lemma to 442 and 1, to get

442 = 1 x 442 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 442 is 1

Notice that 1 = HCF(442,1) .
