HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 437, 989 i.e. 23 the largest integer that leaves a remainder zero for all numbers.
HCF of 437, 989 is 23 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 437, 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 437, 989 is 23.
HCF(437, 989) = 23
HCF of 437, 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 437, 989 is 23.
Highest Common Factor of 437,989 is 23
Step 1: Since 989 > 437, we apply the division lemma to 989 and 437, to get
989 = 437 x 2 + 115
Step 2: Since the reminder 437 ≠ 0, we apply division lemma to 115 and 437, to get
437 = 115 x 3 + 92
Step 3: We consider the new divisor 115 and the new remainder 92, and apply the division lemma to get
115 = 92 x 1 + 23
We consider the new divisor 92 and the new remainder 23, and apply the division lemma to get
92 = 23 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 23, the HCF of 437 and 989 is 23
Notice that 23 = HCF(92,23) = HCF(115,92) = HCF(437,115) = HCF(989,437) .
