HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 414, 981, 932, 468 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 414, 981, 932, 468 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 414, 981, 932, 468 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 414, 981, 932, 468 is 1.
HCF(414, 981, 932, 468) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 414, 981, 932, 468 is 1.
Step 1: Since 981 > 414, we apply the division lemma to 981 and 414, to get
981 = 414 x 2 + 153
Step 2: Since the reminder 414 ≠ 0, we apply division lemma to 153 and 414, to get
414 = 153 x 2 + 108
Step 3: We consider the new divisor 153 and the new remainder 108, and apply the division lemma to get
153 = 108 x 1 + 45
We consider the new divisor 108 and the new remainder 45,and apply the division lemma to get
108 = 45 x 2 + 18
We consider the new divisor 45 and the new remainder 18,and apply the division lemma to get
45 = 18 x 2 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 414 and 981 is 9
Notice that 9 = HCF(18,9) = HCF(45,18) = HCF(108,45) = HCF(153,108) = HCF(414,153) = HCF(981,414) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 932 > 9, we apply the division lemma to 932 and 9, to get
932 = 9 x 103 + 5
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 5 and 9, to get
9 = 5 x 1 + 4
Step 3: We consider the new divisor 5 and the new remainder 4, and apply the division lemma to get
5 = 4 x 1 + 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 9 and 932 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(932,9) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 468 > 1, we apply the division lemma to 468 and 1, to get
468 = 1 x 468 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 468 is 1
Notice that 1 = HCF(468,1) .
