HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 372, 217, 63 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 372, 217, 63 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 372, 217, 63 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 372, 217, 63 is 1.
HCF(372, 217, 63) = 1
HCF of 372, 217, 63 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 372, 217, 63 is 1.
Highest Common Factor of 372,217,63 is 1
Step 1: Since 372 > 217, we apply the division lemma to 372 and 217, to get
372 = 217 x 1 + 155
Step 2: Since the reminder 217 ≠ 0, we apply division lemma to 155 and 217, to get
217 = 155 x 1 + 62
Step 3: We consider the new divisor 155 and the new remainder 62, and apply the division lemma to get
155 = 62 x 2 + 31
We consider the new divisor 62 and the new remainder 31, and apply the division lemma to get
62 = 31 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 31, the HCF of 372 and 217 is 31
Notice that 31 = HCF(62,31) = HCF(155,62) = HCF(217,155) = HCF(372,217) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 63 > 31, we apply the division lemma to 63 and 31, to get
63 = 31 x 2 + 1
Step 2: Since the reminder 31 ≠ 0, we apply division lemma to 1 and 31, to get
31 = 1 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 31 and 63 is 1
Notice that 1 = HCF(31,1) = HCF(63,31) .
