HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 831, 507, 702 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 831, 507, 702 is 3 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 831, 507, 702 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 831, 507, 702 is 3.
HCF(831, 507, 702) = 3
HCF of 831, 507, 702 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 831, 507, 702 is 3.
Highest Common Factor of 831,507,702 is 3
Step 1: Since 831 > 507, we apply the division lemma to 831 and 507, to get
831 = 507 x 1 + 324
Step 2: Since the reminder 507 ≠ 0, we apply division lemma to 324 and 507, to get
507 = 324 x 1 + 183
Step 3: We consider the new divisor 324 and the new remainder 183, and apply the division lemma to get
324 = 183 x 1 + 141
We consider the new divisor 183 and the new remainder 141,and apply the division lemma to get
183 = 141 x 1 + 42
We consider the new divisor 141 and the new remainder 42,and apply the division lemma to get
141 = 42 x 3 + 15
We consider the new divisor 42 and the new remainder 15,and apply the division lemma to get
42 = 15 x 2 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 831 and 507 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(42,15) = HCF(141,42) = HCF(183,141) = HCF(324,183) = HCF(507,324) = HCF(831,507) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 702 > 3, we apply the division lemma to 702 and 3, to get
702 = 3 x 234 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 702 is 3
Notice that 3 = HCF(702,3) .
