HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 456 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 869, 456 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 869, 456 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 869, 456 is 1.
HCF(869, 456) = 1
HCF of 869, 456 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 869, 456 is 1.
Highest Common Factor of 869,456 is 1
Step 1: Since 869 > 456, we apply the division lemma to 869 and 456, to get
869 = 456 x 1 + 413
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 413 and 456, to get
456 = 413 x 1 + 43
Step 3: We consider the new divisor 413 and the new remainder 43, and apply the division lemma to get
413 = 43 x 9 + 26
We consider the new divisor 43 and the new remainder 26,and apply the division lemma to get
43 = 26 x 1 + 17
We consider the new divisor 26 and the new remainder 17,and apply the division lemma to get
26 = 17 x 1 + 9
We consider the new divisor 17 and the new remainder 9,and apply the division lemma to get
17 = 9 x 1 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 869 and 456 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(17,9) = HCF(26,17) = HCF(43,26) = HCF(413,43) = HCF(456,413) = HCF(869,456) .
