HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 711, 958, 561, 70 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 711, 958, 561, 70 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 711, 958, 561, 70 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 711, 958, 561, 70 is 1.

HCF(711, 958, 561, 70) = 1

Highest common factor (HCF) of 711, 958, 561, 70 is 1.

Highest Common Factor of 711,958,561,70 using Euclid's algorithm

Highest Common Factor of 711,958,561,70 is 1

Step 1: Since 958 > 711, we apply the division lemma to 958 and 711, to get

958 = 711 x 1 + 247

Step 2: Since the reminder 711 ≠ 0, we apply division lemma to 247 and 711, to get

711 = 247 x 2 + 217

Step 3: We consider the new divisor 247 and the new remainder 217, and apply the division lemma to get

247 = 217 x 1 + 30

We consider the new divisor 217 and the new remainder 30,and apply the division lemma to get

217 = 30 x 7 + 7

We consider the new divisor 30 and the new remainder 7,and apply the division lemma to get

30 = 7 x 4 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 711 and 958 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(30,7) = HCF(217,30) = HCF(247,217) = HCF(711,247) = HCF(958,711) .

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

Step 1: Since 561 > 1, we apply the division lemma to 561 and 1, to get

561 = 1 x 561 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 561 is 1

Notice that 1 = HCF(561,1) .

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

Step 1: Since 70 > 1, we apply the division lemma to 70 and 1, to get

70 = 1 x 70 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 70 is 1

Notice that 1 = HCF(70,1) .
