HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 159, 862, 150, 420 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 159, 862, 150, 420 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 159, 862, 150, 420 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 159, 862, 150, 420 is 1.
HCF(159, 862, 150, 420) = 1
HCF of 159, 862, 150, 420 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 159, 862, 150, 420 is 1.
Highest Common Factor of 159,862,150,420 is 1
Step 1: Since 862 > 159, we apply the division lemma to 862 and 159, to get
862 = 159 x 5 + 67
Step 2: Since the reminder 159 ≠ 0, we apply division lemma to 67 and 159, to get
159 = 67 x 2 + 25
Step 3: We consider the new divisor 67 and the new remainder 25, and apply the division lemma to get
67 = 25 x 2 + 17
We consider the new divisor 25 and the new remainder 17,and apply the division lemma to get
25 = 17 x 1 + 8
We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get
17 = 8 x 2 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 159 and 862 is 1
Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(25,17) = HCF(67,25) = HCF(159,67) = HCF(862,159) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 150 > 1, we apply the division lemma to 150 and 1, to get
150 = 1 x 150 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 150 is 1
Notice that 1 = HCF(150,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 420 > 1, we apply the division lemma to 420 and 1, to get
420 = 1 x 420 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 420 is 1
Notice that 1 = HCF(420,1) .
