HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 434, 188, 891 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 434, 188, 891 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 434, 188, 891 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 434, 188, 891 is 1.
HCF(434, 188, 891) = 1
HCF of 434, 188, 891 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 434, 188, 891 is 1.
Highest Common Factor of 434,188,891 is 1
Step 1: Since 434 > 188, we apply the division lemma to 434 and 188, to get
434 = 188 x 2 + 58
Step 2: Since the reminder 188 ≠ 0, we apply division lemma to 58 and 188, to get
188 = 58 x 3 + 14
Step 3: We consider the new divisor 58 and the new remainder 14, and apply the division lemma to get
58 = 14 x 4 + 2
We consider the new divisor 14 and the new remainder 2, and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 434 and 188 is 2
Notice that 2 = HCF(14,2) = HCF(58,14) = HCF(188,58) = HCF(434,188) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 891 > 2, we apply the division lemma to 891 and 2, to get
891 = 2 x 445 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 891 is 1
Notice that 1 = HCF(2,1) = HCF(891,2) .
