HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 156, 829, 899 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 561, 156, 829, 899 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 561, 156, 829, 899 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 561, 156, 829, 899 is 1.
HCF(561, 156, 829, 899) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 561, 156, 829, 899 is 1.
Step 1: Since 561 > 156, we apply the division lemma to 561 and 156, to get
561 = 156 x 3 + 93
Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 93 and 156, to get
156 = 93 x 1 + 63
Step 3: We consider the new divisor 93 and the new remainder 63, and apply the division lemma to get
93 = 63 x 1 + 30
We consider the new divisor 63 and the new remainder 30,and apply the division lemma to get
63 = 30 x 2 + 3
We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get
30 = 3 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 561 and 156 is 3
Notice that 3 = HCF(30,3) = HCF(63,30) = HCF(93,63) = HCF(156,93) = HCF(561,156) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 829 > 3, we apply the division lemma to 829 and 3, to get
829 = 3 x 276 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 829 is 1
Notice that 1 = HCF(3,1) = HCF(829,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 899 > 1, we apply the division lemma to 899 and 1, to get
899 = 1 x 899 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 899 is 1
Notice that 1 = HCF(899,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
