HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 955, 427, 120, 620 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 955, 427, 120, 620 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 955, 427, 120, 620 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 955, 427, 120, 620 is 1.
HCF(955, 427, 120, 620) = 1
HCF of 955, 427, 120, 620 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 955, 427, 120, 620 is 1.
Highest Common Factor of 955,427,120,620 is 1
Step 1: Since 955 > 427, we apply the division lemma to 955 and 427, to get
955 = 427 x 2 + 101
Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 101 and 427, to get
427 = 101 x 4 + 23
Step 3: We consider the new divisor 101 and the new remainder 23, and apply the division lemma to get
101 = 23 x 4 + 9
We consider the new divisor 23 and the new remainder 9,and apply the division lemma to get
23 = 9 x 2 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 955 and 427 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(23,9) = HCF(101,23) = HCF(427,101) = HCF(955,427) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 120 > 1, we apply the division lemma to 120 and 1, to get
120 = 1 x 120 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 120 is 1
Notice that 1 = HCF(120,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 620 > 1, we apply the division lemma to 620 and 1, to get
620 = 1 x 620 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 620 is 1
Notice that 1 = HCF(620,1) .
