HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 589, 838 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 722, 589, 838 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 722, 589, 838 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 722, 589, 838 is 1.
HCF(722, 589, 838) = 1
HCF of 722, 589, 838 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 722, 589, 838 is 1.
Highest Common Factor of 722,589,838 is 1
Step 1: Since 722 > 589, we apply the division lemma to 722 and 589, to get
722 = 589 x 1 + 133
Step 2: Since the reminder 589 ≠ 0, we apply division lemma to 133 and 589, to get
589 = 133 x 4 + 57
Step 3: We consider the new divisor 133 and the new remainder 57, and apply the division lemma to get
133 = 57 x 2 + 19
We consider the new divisor 57 and the new remainder 19, and apply the division lemma to get
57 = 19 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 722 and 589 is 19
Notice that 19 = HCF(57,19) = HCF(133,57) = HCF(589,133) = HCF(722,589) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 838 > 19, we apply the division lemma to 838 and 19, to get
838 = 19 x 44 + 2
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 2 and 19, to get
19 = 2 x 9 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 19 and 838 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(838,19) .
