HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 703, 985 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 703, 985 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 703, 985 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 703, 985 is 1.
HCF(703, 985) = 1
HCF of 703, 985 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 703, 985 is 1.
Highest Common Factor of 703,985 is 1
Step 1: Since 985 > 703, we apply the division lemma to 985 and 703, to get
985 = 703 x 1 + 282
Step 2: Since the reminder 703 ≠ 0, we apply division lemma to 282 and 703, to get
703 = 282 x 2 + 139
Step 3: We consider the new divisor 282 and the new remainder 139, and apply the division lemma to get
282 = 139 x 2 + 4
We consider the new divisor 139 and the new remainder 4,and apply the division lemma to get
139 = 4 x 34 + 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 703 and 985 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(139,4) = HCF(282,139) = HCF(703,282) = HCF(985,703) .
