HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 495, 868, 254, 85 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 495, 868, 254, 85 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 495, 868, 254, 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 495, 868, 254, 85 is 1.
HCF(495, 868, 254, 85) = 1
HCF of 495, 868, 254, 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 495, 868, 254, 85 is 1.
Highest Common Factor of 495,868,254,85 is 1
Step 1: Since 868 > 495, we apply the division lemma to 868 and 495, to get
868 = 495 x 1 + 373
Step 2: Since the reminder 495 ≠ 0, we apply division lemma to 373 and 495, to get
495 = 373 x 1 + 122
Step 3: We consider the new divisor 373 and the new remainder 122, and apply the division lemma to get
373 = 122 x 3 + 7
We consider the new divisor 122 and the new remainder 7,and apply the division lemma to get
122 = 7 x 17 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 495 and 868 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(122,7) = HCF(373,122) = HCF(495,373) = HCF(868,495) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 254 > 1, we apply the division lemma to 254 and 1, to get
254 = 1 x 254 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 254 is 1
Notice that 1 = HCF(254,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 85 > 1, we apply the division lemma to 85 and 1, to get
85 = 1 x 85 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 85 is 1
Notice that 1 = HCF(85,1) .
