HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 909, 454, 618, 63 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 909, 454, 618, 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 909, 454, 618, 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 909, 454, 618, 63 is 1.
HCF(909, 454, 618, 63) = 1
HCF of 909, 454, 618, 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 909, 454, 618, 63 is 1.
Highest Common Factor of 909,454,618,63 is 1
Step 1: Since 909 > 454, we apply the division lemma to 909 and 454, to get
909 = 454 x 2 + 1
Step 2: Since the reminder 454 ≠ 0, we apply division lemma to 1 and 454, to get
454 = 1 x 454 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 909 and 454 is 1
Notice that 1 = HCF(454,1) = HCF(909,454) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 618 > 1, we apply the division lemma to 618 and 1, to get
618 = 1 x 618 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 618 is 1
Notice that 1 = HCF(618,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 63 > 1, we apply the division lemma to 63 and 1, to get
63 = 1 x 63 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 63 is 1
Notice that 1 = HCF(63,1) .
