HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 942, 597, 824 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 942, 597, 824 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 942, 597, 824 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 942, 597, 824 is 1.
HCF(942, 597, 824) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 942, 597, 824 is 1.
Step 1: Since 942 > 597, we apply the division lemma to 942 and 597, to get
942 = 597 x 1 + 345
Step 2: Since the reminder 597 ≠ 0, we apply division lemma to 345 and 597, to get
597 = 345 x 1 + 252
Step 3: We consider the new divisor 345 and the new remainder 252, and apply the division lemma to get
345 = 252 x 1 + 93
We consider the new divisor 252 and the new remainder 93,and apply the division lemma to get
252 = 93 x 2 + 66
We consider the new divisor 93 and the new remainder 66,and apply the division lemma to get
93 = 66 x 1 + 27
We consider the new divisor 66 and the new remainder 27,and apply the division lemma to get
66 = 27 x 2 + 12
We consider the new divisor 27 and the new remainder 12,and apply the division lemma to get
27 = 12 x 2 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 942 and 597 is 3
Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(66,27) = HCF(93,66) = HCF(252,93) = HCF(345,252) = HCF(597,345) = HCF(942,597) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 824 > 3, we apply the division lemma to 824 and 3, to get
824 = 3 x 274 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: 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 3 and 824 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(824,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
