HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 477, 355, 933, 77 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 477, 355, 933, 77 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 477, 355, 933, 77 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 477, 355, 933, 77 is 1.
HCF(477, 355, 933, 77) = 1
HCF of 477, 355, 933, 77 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 477, 355, 933, 77 is 1.
Highest Common Factor of 477,355,933,77 is 1
Step 1: Since 477 > 355, we apply the division lemma to 477 and 355, to get
477 = 355 x 1 + 122
Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 122 and 355, to get
355 = 122 x 2 + 111
Step 3: We consider the new divisor 122 and the new remainder 111, and apply the division lemma to get
122 = 111 x 1 + 11
We consider the new divisor 111 and the new remainder 11,and apply the division lemma to get
111 = 11 x 10 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 477 and 355 is 1
Notice that 1 = HCF(11,1) = HCF(111,11) = HCF(122,111) = HCF(355,122) = HCF(477,355) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 933 > 1, we apply the division lemma to 933 and 1, to get
933 = 1 x 933 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 933 is 1
Notice that 1 = HCF(933,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 77 > 1, we apply the division lemma to 77 and 1, to get
77 = 1 x 77 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 77 is 1
Notice that 1 = HCF(77,1) .
