HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 675, 957 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 675, 957 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 605, 675, 957 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 605, 675, 957 is 1.
HCF(605, 675, 957) = 1
HCF of 605, 675, 957 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 675, 957 is 1.
Highest Common Factor of 605,675,957 is 1
Step 1: Since 675 > 605, we apply the division lemma to 675 and 605, to get
675 = 605 x 1 + 70
Step 2: Since the reminder 605 ≠ 0, we apply division lemma to 70 and 605, to get
605 = 70 x 8 + 45
Step 3: We consider the new divisor 70 and the new remainder 45, and apply the division lemma to get
70 = 45 x 1 + 25
We consider the new divisor 45 and the new remainder 25,and apply the division lemma to get
45 = 25 x 1 + 20
We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get
25 = 20 x 1 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 605 and 675 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(45,25) = HCF(70,45) = HCF(605,70) = HCF(675,605) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 957 > 5, we apply the division lemma to 957 and 5, to get
957 = 5 x 191 + 2
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get
5 = 2 x 2 + 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 5 and 957 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(957,5) .
