HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 800, 631, 922, 981 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 800, 631, 922, 981 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 800, 631, 922, 981 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 800, 631, 922, 981 is 1.
HCF(800, 631, 922, 981) = 1
HCF of 800, 631, 922, 981 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 800, 631, 922, 981 is 1.
Highest Common Factor of 800,631,922,981 is 1
Step 1: Since 800 > 631, we apply the division lemma to 800 and 631, to get
800 = 631 x 1 + 169
Step 2: Since the reminder 631 ≠ 0, we apply division lemma to 169 and 631, to get
631 = 169 x 3 + 124
Step 3: We consider the new divisor 169 and the new remainder 124, and apply the division lemma to get
169 = 124 x 1 + 45
We consider the new divisor 124 and the new remainder 45,and apply the division lemma to get
124 = 45 x 2 + 34
We consider the new divisor 45 and the new remainder 34,and apply the division lemma to get
45 = 34 x 1 + 11
We consider the new divisor 34 and the new remainder 11,and apply the division lemma to get
34 = 11 x 3 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 800 and 631 is 1
Notice that 1 = HCF(11,1) = HCF(34,11) = HCF(45,34) = HCF(124,45) = HCF(169,124) = HCF(631,169) = HCF(800,631) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 922 > 1, we apply the division lemma to 922 and 1, to get
922 = 1 x 922 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 922 is 1
Notice that 1 = HCF(922,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 981 > 1, we apply the division lemma to 981 and 1, to get
981 = 1 x 981 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 981 is 1
Notice that 1 = HCF(981,1) .
