HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 668, 589, 629 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 668, 589, 629 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 668, 589, 629 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 668, 589, 629 is 1.
HCF(668, 589, 629) = 1
HCF of 668, 589, 629 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 668, 589, 629 is 1.
Highest Common Factor of 668,589,629 is 1
Step 1: Since 668 > 589, we apply the division lemma to 668 and 589, to get
668 = 589 x 1 + 79
Step 2: Since the reminder 589 ≠ 0, we apply division lemma to 79 and 589, to get
589 = 79 x 7 + 36
Step 3: We consider the new divisor 79 and the new remainder 36, and apply the division lemma to get
79 = 36 x 2 + 7
We consider the new divisor 36 and the new remainder 7,and apply the division lemma to get
36 = 7 x 5 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 668 and 589 is 1
Notice that 1 = HCF(7,1) = HCF(36,7) = HCF(79,36) = HCF(589,79) = HCF(668,589) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 629 > 1, we apply the division lemma to 629 and 1, to get
629 = 1 x 629 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 629 is 1
Notice that 1 = HCF(629,1) .
