HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 953, 689, 694 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 953, 689, 694 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 953, 689, 694 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 953, 689, 694 is 1.

HCF(953, 689, 694) = 1

Highest common factor (HCF) of 953, 689, 694 is 1.

Highest Common Factor of 953,689,694 using Euclid's algorithm

Highest Common Factor of 953,689,694 is 1

Step 1: Since 953 > 689, we apply the division lemma to 953 and 689, to get

953 = 689 x 1 + 264

Step 2: Since the reminder 689 ≠ 0, we apply division lemma to 264 and 689, to get

689 = 264 x 2 + 161

Step 3: We consider the new divisor 264 and the new remainder 161, and apply the division lemma to get

264 = 161 x 1 + 103

We consider the new divisor 161 and the new remainder 103,and apply the division lemma to get

161 = 103 x 1 + 58

We consider the new divisor 103 and the new remainder 58,and apply the division lemma to get

103 = 58 x 1 + 45

We consider the new divisor 58 and the new remainder 45,and apply the division lemma to get

58 = 45 x 1 + 13

We consider the new divisor 45 and the new remainder 13,and apply the division lemma to get

45 = 13 x 3 + 6

We consider the new divisor 13 and the new remainder 6,and apply the division lemma to get

13 = 6 x 2 + 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 953 and 689 is 1

Notice that 1 = HCF(6,1) = HCF(13,6) = HCF(45,13) = HCF(58,45) = HCF(103,58) = HCF(161,103) = HCF(264,161) = HCF(689,264) = HCF(953,689) .

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

Step 1: Since 694 > 1, we apply the division lemma to 694 and 1, to get

694 = 1 x 694 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 694 is 1

Notice that 1 = HCF(694,1) .
