HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 595, 725, 620, 31 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 595, 725, 620, 31 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 595, 725, 620, 31 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 595, 725, 620, 31 is 1.
HCF(595, 725, 620, 31) = 1
HCF of 595, 725, 620, 31 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 595, 725, 620, 31 is 1.
Highest Common Factor of 595,725,620,31 is 1
Step 1: Since 725 > 595, we apply the division lemma to 725 and 595, to get
725 = 595 x 1 + 130
Step 2: Since the reminder 595 ≠ 0, we apply division lemma to 130 and 595, to get
595 = 130 x 4 + 75
Step 3: We consider the new divisor 130 and the new remainder 75, and apply the division lemma to get
130 = 75 x 1 + 55
We consider the new divisor 75 and the new remainder 55,and apply the division lemma to get
75 = 55 x 1 + 20
We consider the new divisor 55 and the new remainder 20,and apply the division lemma to get
55 = 20 x 2 + 15
We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get
20 = 15 x 1 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 595 and 725 is 5
Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(55,20) = HCF(75,55) = HCF(130,75) = HCF(595,130) = HCF(725,595) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 620 > 5, we apply the division lemma to 620 and 5, to get
620 = 5 x 124 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 620 is 5
Notice that 5 = HCF(620,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 31 > 5, we apply the division lemma to 31 and 5, to get
31 = 5 x 6 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, 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 5 and 31 is 1
Notice that 1 = HCF(5,1) = HCF(31,5) .
