HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 679, 946, 666 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 679, 946, 666 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 679, 946, 666 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 679, 946, 666 is 1.

HCF(679, 946, 666) = 1

HCF of 679, 946, 666 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 679, 946, 666 is 1.

Highest Common Factor of 679,946,666 using Euclid's algorithm

Highest Common Factor of 679,946,666 is 1

Step 1: Since 946 > 679, we apply the division lemma to 946 and 679, to get

946 = 679 x 1 + 267

Step 2: Since the reminder 679 ≠ 0, we apply division lemma to 267 and 679, to get

679 = 267 x 2 + 145

Step 3: We consider the new divisor 267 and the new remainder 145, and apply the division lemma to get

267 = 145 x 1 + 122

We consider the new divisor 145 and the new remainder 122,and apply the division lemma to get

145 = 122 x 1 + 23

We consider the new divisor 122 and the new remainder 23,and apply the division lemma to get

122 = 23 x 5 + 7

We consider the new divisor 23 and the new remainder 7,and apply the division lemma to get

23 = 7 x 3 + 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 679 and 946 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(23,7) = HCF(122,23) = HCF(145,122) = HCF(267,145) = HCF(679,267) = HCF(946,679) .

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

Step 1: Since 666 > 1, we apply the division lemma to 666 and 1, to get

666 = 1 x 666 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 666 is 1

Notice that 1 = HCF(666,1) .
