HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 234, 849, 128 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 234, 849, 128 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 234, 849, 128 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 234, 849, 128 is 1.
HCF(234, 849, 128) = 1
HCF of 234, 849, 128 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 234, 849, 128 is 1.
Highest Common Factor of 234,849,128 is 1
Step 1: Since 849 > 234, we apply the division lemma to 849 and 234, to get
849 = 234 x 3 + 147
Step 2: Since the reminder 234 ≠ 0, we apply division lemma to 147 and 234, to get
234 = 147 x 1 + 87
Step 3: We consider the new divisor 147 and the new remainder 87, and apply the division lemma to get
147 = 87 x 1 + 60
We consider the new divisor 87 and the new remainder 60,and apply the division lemma to get
87 = 60 x 1 + 27
We consider the new divisor 60 and the new remainder 27,and apply the division lemma to get
60 = 27 x 2 + 6
We consider the new divisor 27 and the new remainder 6,and apply the division lemma to get
27 = 6 x 4 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 234 and 849 is 3
Notice that 3 = HCF(6,3) = HCF(27,6) = HCF(60,27) = HCF(87,60) = HCF(147,87) = HCF(234,147) = HCF(849,234) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 128 > 3, we apply the division lemma to 128 and 3, to get
128 = 3 x 42 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 128 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(128,3) .
