HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 616, 955, 915, 945 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 616, 955, 915, 945 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 616, 955, 915, 945 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 616, 955, 915, 945 is 1.
HCF(616, 955, 915, 945) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 616, 955, 915, 945 is 1.
Step 1: Since 955 > 616, we apply the division lemma to 955 and 616, to get
955 = 616 x 1 + 339
Step 2: Since the reminder 616 ≠ 0, we apply division lemma to 339 and 616, to get
616 = 339 x 1 + 277
Step 3: We consider the new divisor 339 and the new remainder 277, and apply the division lemma to get
339 = 277 x 1 + 62
We consider the new divisor 277 and the new remainder 62,and apply the division lemma to get
277 = 62 x 4 + 29
We consider the new divisor 62 and the new remainder 29,and apply the division lemma to get
62 = 29 x 2 + 4
We consider the new divisor 29 and the new remainder 4,and apply the division lemma to get
29 = 4 x 7 + 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 616 and 955 is 1
Notice that 1 = HCF(4,1) = HCF(29,4) = HCF(62,29) = HCF(277,62) = HCF(339,277) = HCF(616,339) = HCF(955,616) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 915 > 1, we apply the division lemma to 915 and 1, to get
915 = 1 x 915 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 915 is 1
Notice that 1 = HCF(915,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 945 > 1, we apply the division lemma to 945 and 1, to get
945 = 1 x 945 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 945 is 1
Notice that 1 = HCF(945,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
