HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 975, 875, 85 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 975, 875, 85 is 5 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 975, 875, 85 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 975, 875, 85 is 5.
HCF(975, 875, 85) = 5
HCF of 975, 875, 85 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 975, 875, 85 is 5.
Highest Common Factor of 975,875,85 is 5
Step 1: Since 975 > 875, we apply the division lemma to 975 and 875, to get
975 = 875 x 1 + 100
Step 2: Since the reminder 875 ≠ 0, we apply division lemma to 100 and 875, to get
875 = 100 x 8 + 75
Step 3: We consider the new divisor 100 and the new remainder 75, and apply the division lemma to get
100 = 75 x 1 + 25
We consider the new divisor 75 and the new remainder 25, and apply the division lemma to get
75 = 25 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 25, the HCF of 975 and 875 is 25
Notice that 25 = HCF(75,25) = HCF(100,75) = HCF(875,100) = HCF(975,875) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 85 > 25, we apply the division lemma to 85 and 25, to get
85 = 25 x 3 + 10
Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 10 and 25, to get
25 = 10 x 2 + 5
Step 3: We consider the new divisor 10 and the new remainder 5, and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 25 and 85 is 5
Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(85,25) .
