HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 674, 989 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 674, 989 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 674, 989 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 674, 989 is 1.
HCF(674, 989) = 1
HCF of 674, 989 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 674, 989 is 1.
Highest Common Factor of 674,989 is 1
Step 1: Since 989 > 674, we apply the division lemma to 989 and 674, to get
989 = 674 x 1 + 315
Step 2: Since the reminder 674 ≠ 0, we apply division lemma to 315 and 674, to get
674 = 315 x 2 + 44
Step 3: We consider the new divisor 315 and the new remainder 44, and apply the division lemma to get
315 = 44 x 7 + 7
We consider the new divisor 44 and the new remainder 7,and apply the division lemma to get
44 = 7 x 6 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 674 and 989 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(44,7) = HCF(315,44) = HCF(674,315) = HCF(989,674) .
