HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 142, 842 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 142, 842 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 142, 842 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 142, 842 is 2.
HCF(142, 842) = 2
HCF of 142, 842 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 142, 842 is 2.
Highest Common Factor of 142,842 is 2
Step 1: Since 842 > 142, we apply the division lemma to 842 and 142, to get
842 = 142 x 5 + 132
Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 132 and 142, to get
142 = 132 x 1 + 10
Step 3: We consider the new divisor 132 and the new remainder 10, and apply the division lemma to get
132 = 10 x 13 + 2
We consider the new divisor 10 and the new remainder 2, and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 142 and 842 is 2
Notice that 2 = HCF(10,2) = HCF(132,10) = HCF(142,132) = HCF(842,142) .
