HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 971, 668, 654, 173 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 971, 668, 654, 173 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 971, 668, 654, 173 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 971, 668, 654, 173 is 1.

HCF(971, 668, 654, 173) = 1

Highest Common Factor of 971,668,654,173 using Euclid's algorithm

Highest Common Factor of 971,668,654,173 is 1

Step 1: Since 971 > 668, we apply the division lemma to 971 and 668, to get

971 = 668 x 1 + 303

Step 2: Since the reminder 668 ≠ 0, we apply division lemma to 303 and 668, to get

668 = 303 x 2 + 62

Step 3: We consider the new divisor 303 and the new remainder 62, and apply the division lemma to get

303 = 62 x 4 + 55

We consider the new divisor 62 and the new remainder 55,and apply the division lemma to get

62 = 55 x 1 + 7

We consider the new divisor 55 and the new remainder 7,and apply the division lemma to get

55 = 7 x 7 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 971 and 668 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(55,7) = HCF(62,55) = HCF(303,62) = HCF(668,303) = HCF(971,668) .

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

Step 1: Since 654 > 1, we apply the division lemma to 654 and 1, to get

654 = 1 x 654 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 654 is 1

Notice that 1 = HCF(654,1) .

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

Step 1: Since 173 > 1, we apply the division lemma to 173 and 1, to get

173 = 1 x 173 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 173 is 1

Notice that 1 = HCF(173,1) .
