HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 340, 542 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 340, 542 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 340, 542 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 340, 542 is 2.
HCF(340, 542) = 2
HCF of 340, 542 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 340, 542 is 2.
Highest Common Factor of 340,542 is 2
Step 1: Since 542 > 340, we apply the division lemma to 542 and 340, to get
542 = 340 x 1 + 202
Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 202 and 340, to get
340 = 202 x 1 + 138
Step 3: We consider the new divisor 202 and the new remainder 138, and apply the division lemma to get
202 = 138 x 1 + 64
We consider the new divisor 138 and the new remainder 64,and apply the division lemma to get
138 = 64 x 2 + 10
We consider the new divisor 64 and the new remainder 10,and apply the division lemma to get
64 = 10 x 6 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 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 340 and 542 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(64,10) = HCF(138,64) = HCF(202,138) = HCF(340,202) = HCF(542,340) .
