HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 564, 476, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 564, 476, 781 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 564, 476, 781 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 564, 476, 781 is 1.
HCF(564, 476, 781) = 1
HCF of 564, 476, 781 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 564, 476, 781 is 1.
Highest Common Factor of 564,476,781 is 1
Step 1: Since 564 > 476, we apply the division lemma to 564 and 476, to get
564 = 476 x 1 + 88
Step 2: Since the reminder 476 ≠ 0, we apply division lemma to 88 and 476, to get
476 = 88 x 5 + 36
Step 3: We consider the new divisor 88 and the new remainder 36, and apply the division lemma to get
88 = 36 x 2 + 16
We consider the new divisor 36 and the new remainder 16,and apply the division lemma to get
36 = 16 x 2 + 4
We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 564 and 476 is 4
Notice that 4 = HCF(16,4) = HCF(36,16) = HCF(88,36) = HCF(476,88) = HCF(564,476) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 781 > 4, we apply the division lemma to 781 and 4, to get
781 = 4 x 195 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, 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 4 and 781 is 1
Notice that 1 = HCF(4,1) = HCF(781,4) .
