HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 924, 565, 140, 156 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 924, 565, 140, 156 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 924, 565, 140, 156 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 924, 565, 140, 156 is 1.
HCF(924, 565, 140, 156) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 924, 565, 140, 156 is 1.
Step 1: Since 924 > 565, we apply the division lemma to 924 and 565, to get
924 = 565 x 1 + 359
Step 2: Since the reminder 565 ≠ 0, we apply division lemma to 359 and 565, to get
565 = 359 x 1 + 206
Step 3: We consider the new divisor 359 and the new remainder 206, and apply the division lemma to get
359 = 206 x 1 + 153
We consider the new divisor 206 and the new remainder 153,and apply the division lemma to get
206 = 153 x 1 + 53
We consider the new divisor 153 and the new remainder 53,and apply the division lemma to get
153 = 53 x 2 + 47
We consider the new divisor 53 and the new remainder 47,and apply the division lemma to get
53 = 47 x 1 + 6
We consider the new divisor 47 and the new remainder 6,and apply the division lemma to get
47 = 6 x 7 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 924 and 565 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(47,6) = HCF(53,47) = HCF(153,53) = HCF(206,153) = HCF(359,206) = HCF(565,359) = HCF(924,565) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 140 > 1, we apply the division lemma to 140 and 1, to get
140 = 1 x 140 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 140 is 1
Notice that 1 = HCF(140,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 156 > 1, we apply the division lemma to 156 and 1, to get
156 = 1 x 156 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 156 is 1
Notice that 1 = HCF(156,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
