HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 598, 644, 961, 662 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 598, 644, 961, 662 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 598, 644, 961, 662 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 598, 644, 961, 662 is 1.
HCF(598, 644, 961, 662) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 598, 644, 961, 662 is 1.
Step 1: Since 644 > 598, we apply the division lemma to 644 and 598, to get
644 = 598 x 1 + 46
Step 2: Since the reminder 598 ≠ 0, we apply division lemma to 46 and 598, to get
598 = 46 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 46, the HCF of 598 and 644 is 46
Notice that 46 = HCF(598,46) = HCF(644,598) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 961 > 46, we apply the division lemma to 961 and 46, to get
961 = 46 x 20 + 41
Step 2: Since the reminder 46 ≠ 0, we apply division lemma to 41 and 46, to get
46 = 41 x 1 + 5
Step 3: We consider the new divisor 41 and the new remainder 5, and apply the division lemma to get
41 = 5 x 8 + 1
We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 46 and 961 is 1
Notice that 1 = HCF(5,1) = HCF(41,5) = HCF(46,41) = HCF(961,46) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 662 > 1, we apply the division lemma to 662 and 1, to get
662 = 1 x 662 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 662 is 1
Notice that 1 = HCF(662,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
