HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 942, 423 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 942, 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 942, 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 942, 423 is 3.
HCF(942, 423) = 3
HCF of 942, 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 942, 423 is 3.
Highest Common Factor of 942,423 is 3
Step 1: Since 942 > 423, we apply the division lemma to 942 and 423, to get
942 = 423 x 2 + 96
Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 96 and 423, to get
423 = 96 x 4 + 39
Step 3: We consider the new divisor 96 and the new remainder 39, and apply the division lemma to get
96 = 39 x 2 + 18
We consider the new divisor 39 and the new remainder 18,and apply the division lemma to get
39 = 18 x 2 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 942 and 423 is 3
Notice that 3 = HCF(18,3) = HCF(39,18) = HCF(96,39) = HCF(423,96) = HCF(942,423) .
