HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1986, 1193 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 1986, 1193 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 1986, 1193 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 1986, 1193 is 1.
HCF(1986, 1193) = 1
HCF of 1986, 1193 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1986, 1193 is 1.
Highest Common Factor of 1986,1193 is 1
Step 1: Since 1986 > 1193, we apply the division lemma to 1986 and 1193, to get
1986 = 1193 x 1 + 793
Step 2: Since the reminder 1193 ≠ 0, we apply division lemma to 793 and 1193, to get
1193 = 793 x 1 + 400
Step 3: We consider the new divisor 793 and the new remainder 400, and apply the division lemma to get
793 = 400 x 1 + 393
We consider the new divisor 400 and the new remainder 393,and apply the division lemma to get
400 = 393 x 1 + 7
We consider the new divisor 393 and the new remainder 7,and apply the division lemma to get
393 = 7 x 56 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1986 and 1193 is 1
Notice that 1 = HCF(7,1) = HCF(393,7) = HCF(400,393) = HCF(793,400) = HCF(1193,793) = HCF(1986,1193) .
