HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 629 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 869, 629 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, 629 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, 629 is 1.
HCF(869, 629) = 1
HCF of 869, 629 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, 629 is 1.
Highest Common Factor of 869,629 is 1
Step 1: Since 869 > 629, we apply the division lemma to 869 and 629, to get
869 = 629 x 1 + 240
Step 2: Since the reminder 629 ≠ 0, we apply division lemma to 240 and 629, to get
629 = 240 x 2 + 149
Step 3: We consider the new divisor 240 and the new remainder 149, and apply the division lemma to get
240 = 149 x 1 + 91
We consider the new divisor 149 and the new remainder 91,and apply the division lemma to get
149 = 91 x 1 + 58
We consider the new divisor 91 and the new remainder 58,and apply the division lemma to get
91 = 58 x 1 + 33
We consider the new divisor 58 and the new remainder 33,and apply the division lemma to get
58 = 33 x 1 + 25
We consider the new divisor 33 and the new remainder 25,and apply the division lemma to get
33 = 25 x 1 + 8
We consider the new divisor 25 and the new remainder 8,and apply the division lemma to get
25 = 8 x 3 + 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 629 is 1
Notice that 1 = HCF(8,1) = HCF(25,8) = HCF(33,25) = HCF(58,33) = HCF(91,58) = HCF(149,91) = HCF(240,149) = HCF(629,240) = HCF(869,629) .
