HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 648, 835, 947 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 648, 835, 947 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 648, 835, 947 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 648, 835, 947 is 1.

HCF(648, 835, 947) = 1

Highest common factor (HCF) of 648, 835, 947 is 1.

Highest Common Factor of 648,835,947 using Euclid's algorithm

Highest Common Factor of 648,835,947 is 1

Step 1: Since 835 > 648, we apply the division lemma to 835 and 648, to get

835 = 648 x 1 + 187

Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 187 and 648, to get

648 = 187 x 3 + 87

Step 3: We consider the new divisor 187 and the new remainder 87, and apply the division lemma to get

187 = 87 x 2 + 13

We consider the new divisor 87 and the new remainder 13,and apply the division lemma to get

87 = 13 x 6 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 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 648 and 835 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(87,13) = HCF(187,87) = HCF(648,187) = HCF(835,648) .

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

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

947 = 1 x 947 + 0

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

Notice that 1 = HCF(947,1) .
