HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 447, 777, 100, 52 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 447, 777, 100, 52 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 447, 777, 100, 52 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 447, 777, 100, 52 is 1.
HCF(447, 777, 100, 52) = 1
HCF of 447, 777, 100, 52 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 447, 777, 100, 52 is 1.
Highest Common Factor of 447,777,100,52 is 1
Step 1: Since 777 > 447, we apply the division lemma to 777 and 447, to get
777 = 447 x 1 + 330
Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 330 and 447, to get
447 = 330 x 1 + 117
Step 3: We consider the new divisor 330 and the new remainder 117, and apply the division lemma to get
330 = 117 x 2 + 96
We consider the new divisor 117 and the new remainder 96,and apply the division lemma to get
117 = 96 x 1 + 21
We consider the new divisor 96 and the new remainder 21,and apply the division lemma to get
96 = 21 x 4 + 12
We consider the new divisor 21 and the new remainder 12,and apply the division lemma to get
21 = 12 x 1 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 447 and 777 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(96,21) = HCF(117,96) = HCF(330,117) = HCF(447,330) = HCF(777,447) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 100 > 3, we apply the division lemma to 100 and 3, to get
100 = 3 x 33 + 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 100 is 1
Notice that 1 = HCF(3,1) = HCF(100,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 52 > 1, we apply the division lemma to 52 and 1, to get
52 = 1 x 52 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 52 is 1
Notice that 1 = HCF(52,1) .
