HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 527, 679, 21, 609 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 527, 679, 21, 609 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 527, 679, 21, 609 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 527, 679, 21, 609 is 1.
HCF(527, 679, 21, 609) = 1
HCF of 527, 679, 21, 609 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 527, 679, 21, 609 is 1.
Highest Common Factor of 527,679,21,609 is 1
Step 1: Since 679 > 527, we apply the division lemma to 679 and 527, to get
679 = 527 x 1 + 152
Step 2: Since the reminder 527 ≠ 0, we apply division lemma to 152 and 527, to get
527 = 152 x 3 + 71
Step 3: We consider the new divisor 152 and the new remainder 71, and apply the division lemma to get
152 = 71 x 2 + 10
We consider the new divisor 71 and the new remainder 10,and apply the division lemma to get
71 = 10 x 7 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 527 and 679 is 1
Notice that 1 = HCF(10,1) = HCF(71,10) = HCF(152,71) = HCF(527,152) = HCF(679,527) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 21 > 1, we apply the division lemma to 21 and 1, to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 21 is 1
Notice that 1 = HCF(21,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 609 > 1, we apply the division lemma to 609 and 1, to get
609 = 1 x 609 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 609 is 1
Notice that 1 = HCF(609,1) .
