HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 861, 629, 591, 951 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 861, 629, 591, 951 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 861, 629, 591, 951 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 861, 629, 591, 951 is 1.
HCF(861, 629, 591, 951) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 861, 629, 591, 951 is 1.
Step 1: Since 861 > 629, we apply the division lemma to 861 and 629, to get
861 = 629 x 1 + 232
Step 2: Since the reminder 629 ≠ 0, we apply division lemma to 232 and 629, to get
629 = 232 x 2 + 165
Step 3: We consider the new divisor 232 and the new remainder 165, and apply the division lemma to get
232 = 165 x 1 + 67
We consider the new divisor 165 and the new remainder 67,and apply the division lemma to get
165 = 67 x 2 + 31
We consider the new divisor 67 and the new remainder 31,and apply the division lemma to get
67 = 31 x 2 + 5
We consider the new divisor 31 and the new remainder 5,and apply the division lemma to get
31 = 5 x 6 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 861 and 629 is 1
Notice that 1 = HCF(5,1) = HCF(31,5) = HCF(67,31) = HCF(165,67) = HCF(232,165) = HCF(629,232) = HCF(861,629) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 591 > 1, we apply the division lemma to 591 and 1, to get
591 = 1 x 591 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 591 is 1
Notice that 1 = HCF(591,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 951 > 1, we apply the division lemma to 951 and 1, to get
951 = 1 x 951 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 951 is 1
Notice that 1 = HCF(951,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
