HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 142, 1585 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 142, 1585 is 1 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, 1585 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, 1585 is 1.
HCF(142, 1585) = 1
HCF of 142, 1585 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, 1585 is 1.
Highest Common Factor of 142,1585 is 1
Step 1: Since 1585 > 142, we apply the division lemma to 1585 and 142, to get
1585 = 142 x 11 + 23
Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 23 and 142, to get
142 = 23 x 6 + 4
Step 3: We consider the new divisor 23 and the new remainder 4, and apply the division lemma to get
23 = 4 x 5 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 142 and 1585 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(23,4) = HCF(142,23) = HCF(1585,142) .
