HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 428, 359, 842, 136 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 428, 359, 842, 136 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 428, 359, 842, 136 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 428, 359, 842, 136 is 1.
HCF(428, 359, 842, 136) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 428, 359, 842, 136 is 1.
Step 1: Since 428 > 359, we apply the division lemma to 428 and 359, to get
428 = 359 x 1 + 69
Step 2: Since the reminder 359 ≠ 0, we apply division lemma to 69 and 359, to get
359 = 69 x 5 + 14
Step 3: We consider the new divisor 69 and the new remainder 14, and apply the division lemma to get
69 = 14 x 4 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 428 and 359 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(69,14) = HCF(359,69) = HCF(428,359) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 842 > 1, we apply the division lemma to 842 and 1, to get
842 = 1 x 842 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 842 is 1
Notice that 1 = HCF(842,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 136 > 1, we apply the division lemma to 136 and 1, to get
136 = 1 x 136 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 136 is 1
Notice that 1 = HCF(136,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
