HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 804, 73 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 949, 804, 73 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, 804, 73 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, 804, 73 is 1.

HCF(949, 804, 73) = 1

Highest common factor (HCF) of 949, 804, 73 is 1.

Highest Common Factor of 949,804,73 using Euclid's algorithm

Highest Common Factor of 949,804,73 is 1

Step 1: Since 949 > 804, we apply the division lemma to 949 and 804, to get

949 = 804 x 1 + 145

Step 2: Since the reminder 804 ≠ 0, we apply division lemma to 145 and 804, to get

804 = 145 x 5 + 79

Step 3: We consider the new divisor 145 and the new remainder 79, and apply the division lemma to get

145 = 79 x 1 + 66

We consider the new divisor 79 and the new remainder 66,and apply the division lemma to get

79 = 66 x 1 + 13

We consider the new divisor 66 and the new remainder 13,and apply the division lemma to get

66 = 13 x 5 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 949 and 804 is 1

Notice that 1 = HCF(13,1) = HCF(66,13) = HCF(79,66) = HCF(145,79) = HCF(804,145) = HCF(949,804) .

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

Step 1: Since 73 > 1, we apply the division lemma to 73 and 1, to get

73 = 1 x 73 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 73 is 1

Notice that 1 = HCF(73,1) .
