HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 245, 403, 160, 866 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 245, 403, 160, 866 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 245, 403, 160, 866 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 245, 403, 160, 866 is 1.
HCF(245, 403, 160, 866) = 1
HCF of 245, 403, 160, 866 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 245, 403, 160, 866 is 1.
Highest Common Factor of 245,403,160,866 is 1
Step 1: Since 403 > 245, we apply the division lemma to 403 and 245, to get
403 = 245 x 1 + 158
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 158 and 245, to get
245 = 158 x 1 + 87
Step 3: We consider the new divisor 158 and the new remainder 87, and apply the division lemma to get
158 = 87 x 1 + 71
We consider the new divisor 87 and the new remainder 71,and apply the division lemma to get
87 = 71 x 1 + 16
We consider the new divisor 71 and the new remainder 16,and apply the division lemma to get
71 = 16 x 4 + 7
We consider the new divisor 16 and the new remainder 7,and apply the division lemma to get
16 = 7 x 2 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
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 245 and 403 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(16,7) = HCF(71,16) = HCF(87,71) = HCF(158,87) = HCF(245,158) = HCF(403,245) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 160 > 1, we apply the division lemma to 160 and 1, to get
160 = 1 x 160 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 160 is 1
Notice that 1 = HCF(160,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 866 > 1, we apply the division lemma to 866 and 1, to get
866 = 1 x 866 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 866 is 1
Notice that 1 = HCF(866,1) .
