HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 670, 520 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 947, 670, 520 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, 670, 520 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, 670, 520 is 1.

HCF(947, 670, 520) = 1

Highest common factor (HCF) of 947, 670, 520 is 1.

Highest Common Factor of 947,670,520 using Euclid's algorithm

Highest Common Factor of 947,670,520 is 1

Step 1: Since 947 > 670, we apply the division lemma to 947 and 670, to get

947 = 670 x 1 + 277

Step 2: Since the reminder 670 ≠ 0, we apply division lemma to 277 and 670, to get

670 = 277 x 2 + 116

Step 3: We consider the new divisor 277 and the new remainder 116, and apply the division lemma to get

277 = 116 x 2 + 45

We consider the new divisor 116 and the new remainder 45,and apply the division lemma to get

116 = 45 x 2 + 26

We consider the new divisor 45 and the new remainder 26,and apply the division lemma to get

45 = 26 x 1 + 19

We consider the new divisor 26 and the new remainder 19,and apply the division lemma to get

26 = 19 x 1 + 7

We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get

19 = 7 x 2 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 670 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(26,19) = HCF(45,26) = HCF(116,45) = HCF(277,116) = HCF(670,277) = HCF(947,670) .

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

Step 1: Since 520 > 1, we apply the division lemma to 520 and 1, to get

520 = 1 x 520 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 520 is 1

Notice that 1 = HCF(520,1) .
