HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 806, 900 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 947, 806, 900 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, 806, 900 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, 806, 900 is 1.

HCF(947, 806, 900) = 1

HCF of 947, 806, 900 using Euclid's algorithm

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

Highest common factor (HCF) of 947, 806, 900 is 1.

Highest Common Factor of 947,806,900 using Euclid's algorithm

Highest Common Factor of 947,806,900 is 1

Step 1: Since 947 > 806, we apply the division lemma to 947 and 806, to get

947 = 806 x 1 + 141

Step 2: Since the reminder 806 ≠ 0, we apply division lemma to 141 and 806, to get

806 = 141 x 5 + 101

Step 3: We consider the new divisor 141 and the new remainder 101, and apply the division lemma to get

141 = 101 x 1 + 40

We consider the new divisor 101 and the new remainder 40,and apply the division lemma to get

101 = 40 x 2 + 21

We consider the new divisor 40 and the new remainder 21,and apply the division lemma to get

40 = 21 x 1 + 19

We consider the new divisor 21 and the new remainder 19,and apply the division lemma to get

21 = 19 x 1 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 947 and 806 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(21,19) = HCF(40,21) = HCF(101,40) = HCF(141,101) = HCF(806,141) = HCF(947,806) .

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

Step 1: Since 900 > 1, we apply the division lemma to 900 and 1, to get

900 = 1 x 900 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 900 is 1

Notice that 1 = HCF(900,1) .
