HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 918, 307 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 918, 307 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 432, 918, 307 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 432, 918, 307 is 1.
HCF(432, 918, 307) = 1
HCF of 432, 918, 307 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 432, 918, 307 is 1.
Highest Common Factor of 432,918,307 is 1
Step 1: Since 918 > 432, we apply the division lemma to 918 and 432, to get
918 = 432 x 2 + 54
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 54 and 432, to get
432 = 54 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 54, the HCF of 432 and 918 is 54
Notice that 54 = HCF(432,54) = HCF(918,432) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 307 > 54, we apply the division lemma to 307 and 54, to get
307 = 54 x 5 + 37
Step 2: Since the reminder 54 ≠ 0, we apply division lemma to 37 and 54, to get
54 = 37 x 1 + 17
Step 3: We consider the new divisor 37 and the new remainder 17, and apply the division lemma to get
37 = 17 x 2 + 3
We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get
17 = 3 x 5 + 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 54 and 307 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(37,17) = HCF(54,37) = HCF(307,54) .
