HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 651, 726 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 651, 726 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 870, 651, 726 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 870, 651, 726 is 3.
HCF(870, 651, 726) = 3
HCF of 870, 651, 726 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 651, 726 is 3.
Highest Common Factor of 870,651,726 is 3
Step 1: Since 870 > 651, we apply the division lemma to 870 and 651, to get
870 = 651 x 1 + 219
Step 2: Since the reminder 651 ≠ 0, we apply division lemma to 219 and 651, to get
651 = 219 x 2 + 213
Step 3: We consider the new divisor 219 and the new remainder 213, and apply the division lemma to get
219 = 213 x 1 + 6
We consider the new divisor 213 and the new remainder 6,and apply the division lemma to get
213 = 6 x 35 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 870 and 651 is 3
Notice that 3 = HCF(6,3) = HCF(213,6) = HCF(219,213) = HCF(651,219) = HCF(870,651) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 726 > 3, we apply the division lemma to 726 and 3, to get
726 = 3 x 242 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 726 is 3
Notice that 3 = HCF(726,3) .
