HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 719, 418, 669 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 719, 418, 669 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 719, 418, 669 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 719, 418, 669 is 1.
HCF(719, 418, 669) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 719, 418, 669 is 1.
Step 1: Since 719 > 418, we apply the division lemma to 719 and 418, to get
719 = 418 x 1 + 301
Step 2: Since the reminder 418 ≠ 0, we apply division lemma to 301 and 418, to get
418 = 301 x 1 + 117
Step 3: We consider the new divisor 301 and the new remainder 117, and apply the division lemma to get
301 = 117 x 2 + 67
We consider the new divisor 117 and the new remainder 67,and apply the division lemma to get
117 = 67 x 1 + 50
We consider the new divisor 67 and the new remainder 50,and apply the division lemma to get
67 = 50 x 1 + 17
We consider the new divisor 50 and the new remainder 17,and apply the division lemma to get
50 = 17 x 2 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 719 and 418 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(50,17) = HCF(67,50) = HCF(117,67) = HCF(301,117) = HCF(418,301) = HCF(719,418) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 669 > 1, we apply the division lemma to 669 and 1, to get
669 = 1 x 669 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 669 is 1
Notice that 1 = HCF(669,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
