HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 875, 947, 66 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 511, 875, 947, 66 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 511, 875, 947, 66 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 511, 875, 947, 66 is 1.
HCF(511, 875, 947, 66) = 1
HCF of 511, 875, 947, 66 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 511, 875, 947, 66 is 1.
Highest Common Factor of 511,875,947,66 is 1
Step 1: Since 875 > 511, we apply the division lemma to 875 and 511, to get
875 = 511 x 1 + 364
Step 2: Since the reminder 511 ≠ 0, we apply division lemma to 364 and 511, to get
511 = 364 x 1 + 147
Step 3: We consider the new divisor 364 and the new remainder 147, and apply the division lemma to get
364 = 147 x 2 + 70
We consider the new divisor 147 and the new remainder 70,and apply the division lemma to get
147 = 70 x 2 + 7
We consider the new divisor 70 and the new remainder 7,and apply the division lemma to get
70 = 7 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 511 and 875 is 7
Notice that 7 = HCF(70,7) = HCF(147,70) = HCF(364,147) = HCF(511,364) = HCF(875,511) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 947 > 7, we apply the division lemma to 947 and 7, to get
947 = 7 x 135 + 2
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 2 and 7, to get
7 = 2 x 3 + 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 7 and 947 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(947,7) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 66 > 1, we apply the division lemma to 66 and 1, to get
66 = 1 x 66 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 66 is 1
Notice that 1 = HCF(66,1) .
