HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 667, 766, 949 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 667, 766, 949 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 667, 766, 949 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 667, 766, 949 is 1.
HCF(667, 766, 949) = 1
HCF of 667, 766, 949 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 667, 766, 949 is 1.
Highest Common Factor of 667,766,949 is 1
Step 1: Since 766 > 667, we apply the division lemma to 766 and 667, to get
766 = 667 x 1 + 99
Step 2: Since the reminder 667 ≠ 0, we apply division lemma to 99 and 667, to get
667 = 99 x 6 + 73
Step 3: We consider the new divisor 99 and the new remainder 73, and apply the division lemma to get
99 = 73 x 1 + 26
We consider the new divisor 73 and the new remainder 26,and apply the division lemma to get
73 = 26 x 2 + 21
We consider the new divisor 26 and the new remainder 21,and apply the division lemma to get
26 = 21 x 1 + 5
We consider the new divisor 21 and the new remainder 5,and apply the division lemma to get
21 = 5 x 4 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 667 and 766 is 1
Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(26,21) = HCF(73,26) = HCF(99,73) = HCF(667,99) = HCF(766,667) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 949 > 1, we apply the division lemma to 949 and 1, to get
949 = 1 x 949 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 949 is 1
Notice that 1 = HCF(949,1) .
