HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 30, 870, 423 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 30, 870, 423 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 30, 870, 423 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 30, 870, 423 is 3.
HCF(30, 870, 423) = 3
HCF of 30, 870, 423 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 30, 870, 423 is 3.
Highest Common Factor of 30,870,423 is 3
Step 1: Since 870 > 30, we apply the division lemma to 870 and 30, to get
870 = 30 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 30 and 870 is 30
Notice that 30 = HCF(870,30) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 423 > 30, we apply the division lemma to 423 and 30, to get
423 = 30 x 14 + 3
Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 3 and 30, to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 30 and 423 is 3
Notice that 3 = HCF(30,3) = HCF(423,30) .
