HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 647, 535, 621 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 647, 535, 621 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 647, 535, 621 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 647, 535, 621 is 1.
HCF(647, 535, 621) = 1
HCF of 647, 535, 621 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 647, 535, 621 is 1.
Highest Common Factor of 647,535,621 is 1
Step 1: Since 647 > 535, we apply the division lemma to 647 and 535, to get
647 = 535 x 1 + 112
Step 2: Since the reminder 535 ≠ 0, we apply division lemma to 112 and 535, to get
535 = 112 x 4 + 87
Step 3: We consider the new divisor 112 and the new remainder 87, and apply the division lemma to get
112 = 87 x 1 + 25
We consider the new divisor 87 and the new remainder 25,and apply the division lemma to get
87 = 25 x 3 + 12
We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get
25 = 12 x 2 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma 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 647 and 535 is 1
Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(87,25) = HCF(112,87) = HCF(535,112) = HCF(647,535) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 621 > 1, we apply the division lemma to 621 and 1, to get
621 = 1 x 621 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 621 is 1
Notice that 1 = HCF(621,1) .
