HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 625, 551 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 869, 625, 551 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, 625, 551 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, 625, 551 is 1.
HCF(869, 625, 551) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 869, 625, 551 is 1.
Step 1: Since 869 > 625, we apply the division lemma to 869 and 625, to get
869 = 625 x 1 + 244
Step 2: Since the reminder 625 ≠ 0, we apply division lemma to 244 and 625, to get
625 = 244 x 2 + 137
Step 3: We consider the new divisor 244 and the new remainder 137, and apply the division lemma to get
244 = 137 x 1 + 107
We consider the new divisor 137 and the new remainder 107,and apply the division lemma to get
137 = 107 x 1 + 30
We consider the new divisor 107 and the new remainder 30,and apply the division lemma to get
107 = 30 x 3 + 17
We consider the new divisor 30 and the new remainder 17,and apply the division lemma to get
30 = 17 x 1 + 13
We consider the new divisor 17 and the new remainder 13,and apply the division lemma to get
17 = 13 x 1 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 869 and 625 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(17,13) = HCF(30,17) = HCF(107,30) = HCF(137,107) = HCF(244,137) = HCF(625,244) = HCF(869,625) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 551 > 1, we apply the division lemma to 551 and 1, to get
551 = 1 x 551 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 551 is 1
Notice that 1 = HCF(551,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
