HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 564, 624, 781 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 564, 624, 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, 624, 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, 624, 781 is 1.
HCF(564, 624, 781) = 1
HCF of 564, 624, 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, 624, 781 is 1.
Highest Common Factor of 564,624,781 is 1
Step 1: Since 624 > 564, we apply the division lemma to 624 and 564, to get
624 = 564 x 1 + 60
Step 2: Since the reminder 564 ≠ 0, we apply division lemma to 60 and 564, to get
564 = 60 x 9 + 24
Step 3: We consider the new divisor 60 and the new remainder 24, and apply the division lemma to get
60 = 24 x 2 + 12
We consider the new divisor 24 and the new remainder 12, and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 564 and 624 is 12
Notice that 12 = HCF(24,12) = HCF(60,24) = HCF(564,60) = HCF(624,564) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 781 > 12, we apply the division lemma to 781 and 12, to get
781 = 12 x 65 + 1
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 1 and 12, to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 781 is 1
Notice that 1 = HCF(12,1) = HCF(781,12) .
