HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 316, 983, 615 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 505, 316, 983, 615 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 505, 316, 983, 615 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 505, 316, 983, 615 is 1.
HCF(505, 316, 983, 615) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 505, 316, 983, 615 is 1.
Step 1: Since 505 > 316, we apply the division lemma to 505 and 316, to get
505 = 316 x 1 + 189
Step 2: Since the reminder 316 ≠ 0, we apply division lemma to 189 and 316, to get
316 = 189 x 1 + 127
Step 3: We consider the new divisor 189 and the new remainder 127, and apply the division lemma to get
189 = 127 x 1 + 62
We consider the new divisor 127 and the new remainder 62,and apply the division lemma to get
127 = 62 x 2 + 3
We consider the new divisor 62 and the new remainder 3,and apply the division lemma to get
62 = 3 x 20 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 505 and 316 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(62,3) = HCF(127,62) = HCF(189,127) = HCF(316,189) = HCF(505,316) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 983 > 1, we apply the division lemma to 983 and 1, to get
983 = 1 x 983 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 983 is 1
Notice that 1 = HCF(983,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 615 > 1, we apply the division lemma to 615 and 1, to get
615 = 1 x 615 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 615 is 1
Notice that 1 = HCF(615,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
