HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 679, 964 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 679, 964 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 679, 964 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 679, 964 is 1.
HCF(679, 964) = 1
HCF of 679, 964 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 679, 964 is 1.
Highest Common Factor of 679,964 is 1
Step 1: Since 964 > 679, we apply the division lemma to 964 and 679, to get
964 = 679 x 1 + 285
Step 2: Since the reminder 679 ≠ 0, we apply division lemma to 285 and 679, to get
679 = 285 x 2 + 109
Step 3: We consider the new divisor 285 and the new remainder 109, and apply the division lemma to get
285 = 109 x 2 + 67
We consider the new divisor 109 and the new remainder 67,and apply the division lemma to get
109 = 67 x 1 + 42
We consider the new divisor 67 and the new remainder 42,and apply the division lemma to get
67 = 42 x 1 + 25
We consider the new divisor 42 and the new remainder 25,and apply the division lemma to get
42 = 25 x 1 + 17
We consider the new divisor 25 and the new remainder 17,and apply the division lemma to get
25 = 17 x 1 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 679 and 964 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(25,17) = HCF(42,25) = HCF(67,42) = HCF(109,67) = HCF(285,109) = HCF(679,285) = HCF(964,679) .
