HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 471, 766, 561, 678 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 471, 766, 561, 678 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 471, 766, 561, 678 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 471, 766, 561, 678 is 1.

HCF(471, 766, 561, 678) = 1

Highest common factor (HCF) of 471, 766, 561, 678 is 1.

Highest Common Factor of 471,766,561,678 using Euclid's algorithm

Highest Common Factor of 471,766,561,678 is 1

Step 1: Since 766 > 471, we apply the division lemma to 766 and 471, to get

766 = 471 x 1 + 295

Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 295 and 471, to get

471 = 295 x 1 + 176

Step 3: We consider the new divisor 295 and the new remainder 176, and apply the division lemma to get

295 = 176 x 1 + 119

We consider the new divisor 176 and the new remainder 119,and apply the division lemma to get

176 = 119 x 1 + 57

We consider the new divisor 119 and the new remainder 57,and apply the division lemma to get

119 = 57 x 2 + 5

We consider the new divisor 57 and the new remainder 5,and apply the division lemma to get

57 = 5 x 11 + 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 471 and 766 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(57,5) = HCF(119,57) = HCF(176,119) = HCF(295,176) = HCF(471,295) = HCF(766,471) .

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 678 > 1, we apply the division lemma to 678 and 1, to get

678 = 1 x 678 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 678 is 1

Notice that 1 = HCF(678,1) .
