HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 135, 424, 955, 39 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 135, 424, 955, 39 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 135, 424, 955, 39 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 135, 424, 955, 39 is 1.
HCF(135, 424, 955, 39) = 1
HCF of 135, 424, 955, 39 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 135, 424, 955, 39 is 1.
Highest Common Factor of 135,424,955,39 is 1
Step 1: Since 424 > 135, we apply the division lemma to 424 and 135, to get
424 = 135 x 3 + 19
Step 2: Since the reminder 135 ≠ 0, we apply division lemma to 19 and 135, to get
135 = 19 x 7 + 2
Step 3: We consider the new divisor 19 and the new remainder 2, and apply the division lemma to get
19 = 2 x 9 + 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 135 and 424 is 1
Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(135,19) = HCF(424,135) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 955 > 1, we apply the division lemma to 955 and 1, to get
955 = 1 x 955 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 955 is 1
Notice that 1 = HCF(955,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 39 > 1, we apply the division lemma to 39 and 1, to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 39 is 1
Notice that 1 = HCF(39,1) .
