HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 722, 149, 491, 935 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 722, 149, 491, 935 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, 149, 491, 935 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, 149, 491, 935 is 1.
HCF(722, 149, 491, 935) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 722, 149, 491, 935 is 1.
Step 1: Since 722 > 149, we apply the division lemma to 722 and 149, to get
722 = 149 x 4 + 126
Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 126 and 149, to get
149 = 126 x 1 + 23
Step 3: We consider the new divisor 126 and the new remainder 23, and apply the division lemma to get
126 = 23 x 5 + 11
We consider the new divisor 23 and the new remainder 11,and apply the division lemma to get
23 = 11 x 2 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 722 and 149 is 1
Notice that 1 = HCF(11,1) = HCF(23,11) = HCF(126,23) = HCF(149,126) = HCF(722,149) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 491 > 1, we apply the division lemma to 491 and 1, to get
491 = 1 x 491 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 491 is 1
Notice that 1 = HCF(491,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 935 > 1, we apply the division lemma to 935 and 1, to get
935 = 1 x 935 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 935 is 1
Notice that 1 = HCF(935,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
