HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 448, 851, 947 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 448, 851, 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 448, 851, 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 448, 851, 947 is 1.

HCF(448, 851, 947) = 1

HCF of 448, 851, 947 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 448, 851, 947 is 1.

Highest Common Factor of 448,851,947 using Euclid's algorithm

Highest Common Factor of 448,851,947 is 1

Step 1: Since 851 > 448, we apply the division lemma to 851 and 448, to get

851 = 448 x 1 + 403

Step 2: Since the reminder 448 ≠ 0, we apply division lemma to 403 and 448, to get

448 = 403 x 1 + 45

Step 3: We consider the new divisor 403 and the new remainder 45, and apply the division lemma to get

403 = 45 x 8 + 43

We consider the new divisor 45 and the new remainder 43,and apply the division lemma to get

45 = 43 x 1 + 2

We consider the new divisor 43 and the new remainder 2,and apply the division lemma to get

43 = 2 x 21 + 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 448 and 851 is 1

Notice that 1 = HCF(2,1) = HCF(43,2) = HCF(45,43) = HCF(403,45) = HCF(448,403) = HCF(851,448) .

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) .
