HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 4238 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 542, 4238 is 2 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 542, 4238 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 542, 4238 is 2.
HCF(542, 4238) = 2
HCF of 542, 4238 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 542, 4238 is 2.
Highest Common Factor of 542,4238 is 2
Step 1: Since 4238 > 542, we apply the division lemma to 4238 and 542, to get
4238 = 542 x 7 + 444
Step 2: Since the reminder 542 ≠ 0, we apply division lemma to 444 and 542, to get
542 = 444 x 1 + 98
Step 3: We consider the new divisor 444 and the new remainder 98, and apply the division lemma to get
444 = 98 x 4 + 52
We consider the new divisor 98 and the new remainder 52,and apply the division lemma to get
98 = 52 x 1 + 46
We consider the new divisor 52 and the new remainder 46,and apply the division lemma to get
52 = 46 x 1 + 6
We consider the new divisor 46 and the new remainder 6,and apply the division lemma to get
46 = 6 x 7 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 542 and 4238 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(46,6) = HCF(52,46) = HCF(98,52) = HCF(444,98) = HCF(542,444) = HCF(4238,542) .
