HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 420, 181, 48 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 947, 420, 181, 48 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 947, 420, 181, 48 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 947, 420, 181, 48 is 1.
HCF(947, 420, 181, 48) = 1
HCF of 947, 420, 181, 48 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 947, 420, 181, 48 is 1.
Highest Common Factor of 947,420,181,48 is 1
Step 1: Since 947 > 420, we apply the division lemma to 947 and 420, to get
947 = 420 x 2 + 107
Step 2: Since the reminder 420 ≠ 0, we apply division lemma to 107 and 420, to get
420 = 107 x 3 + 99
Step 3: We consider the new divisor 107 and the new remainder 99, and apply the division lemma to get
107 = 99 x 1 + 8
We consider the new divisor 99 and the new remainder 8,and apply the division lemma to get
99 = 8 x 12 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
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 947 and 420 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(99,8) = HCF(107,99) = HCF(420,107) = HCF(947,420) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 181 > 1, we apply the division lemma to 181 and 1, to get
181 = 1 x 181 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 181 is 1
Notice that 1 = HCF(181,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 48 > 1, we apply the division lemma to 48 and 1, to get
48 = 1 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 48 is 1
Notice that 1 = HCF(48,1) .
