HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 338, 947 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 770, 338, 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 770, 338, 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 770, 338, 947 is 1.

HCF(770, 338, 947) = 1

Highest common factor (HCF) of 770, 338, 947 is 1.

Highest Common Factor of 770,338,947 using Euclid's algorithm

Highest Common Factor of 770,338,947 is 1

Step 1: Since 770 > 338, we apply the division lemma to 770 and 338, to get

770 = 338 x 2 + 94

Step 2: Since the reminder 338 ≠ 0, we apply division lemma to 94 and 338, to get

338 = 94 x 3 + 56

Step 3: We consider the new divisor 94 and the new remainder 56, and apply the division lemma to get

94 = 56 x 1 + 38

We consider the new divisor 56 and the new remainder 38,and apply the division lemma to get

56 = 38 x 1 + 18

We consider the new divisor 38 and the new remainder 18,and apply the division lemma to get

38 = 18 x 2 + 2

We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get

18 = 2 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 770 and 338 is 2

Notice that 2 = HCF(18,2) = HCF(38,18) = HCF(56,38) = HCF(94,56) = HCF(338,94) = HCF(770,338) .

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

Step 1: Since 947 > 2, we apply the division lemma to 947 and 2, to get

947 = 2 x 473 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 947 is 1

Notice that 1 = HCF(2,1) = HCF(947,2) .
