HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 983, 428 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 983, 428 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 983, 428 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 983, 428 is 1.
HCF(983, 428) = 1
HCF of 983, 428 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 983, 428 is 1.
Highest Common Factor of 983,428 is 1
Step 1: Since 983 > 428, we apply the division lemma to 983 and 428, to get
983 = 428 x 2 + 127
Step 2: Since the reminder 428 ≠ 0, we apply division lemma to 127 and 428, to get
428 = 127 x 3 + 47
Step 3: We consider the new divisor 127 and the new remainder 47, and apply the division lemma to get
127 = 47 x 2 + 33
We consider the new divisor 47 and the new remainder 33,and apply the division lemma to get
47 = 33 x 1 + 14
We consider the new divisor 33 and the new remainder 14,and apply the division lemma to get
33 = 14 x 2 + 5
We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get
14 = 5 x 2 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 983 and 428 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(33,14) = HCF(47,33) = HCF(127,47) = HCF(428,127) = HCF(983,428) .
