HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 692, 845 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 949, 692, 845 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 949, 692, 845 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 949, 692, 845 is 1.

HCF(949, 692, 845) = 1

Highest common factor (HCF) of 949, 692, 845 is 1.

Highest Common Factor of 949,692,845 using Euclid's algorithm

Highest Common Factor of 949,692,845 is 1

Step 1: Since 949 > 692, we apply the division lemma to 949 and 692, to get

949 = 692 x 1 + 257

Step 2: Since the reminder 692 ≠ 0, we apply division lemma to 257 and 692, to get

692 = 257 x 2 + 178

Step 3: We consider the new divisor 257 and the new remainder 178, and apply the division lemma to get

257 = 178 x 1 + 79

We consider the new divisor 178 and the new remainder 79,and apply the division lemma to get

178 = 79 x 2 + 20

We consider the new divisor 79 and the new remainder 20,and apply the division lemma to get

79 = 20 x 3 + 19

We consider the new divisor 20 and the new remainder 19,and apply the division lemma to get

20 = 19 x 1 + 1

We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get

19 = 1 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 949 and 692 is 1

Notice that 1 = HCF(19,1) = HCF(20,19) = HCF(79,20) = HCF(178,79) = HCF(257,178) = HCF(692,257) = HCF(949,692) .

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

Step 1: Since 845 > 1, we apply the division lemma to 845 and 1, to get

845 = 1 x 845 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 845 is 1

Notice that 1 = HCF(845,1) .
