HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 390, 653, 532 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 390, 653, 532 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 390, 653, 532 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 390, 653, 532 is 1.
HCF(390, 653, 532) = 1
HCF of 390, 653, 532 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 390, 653, 532 is 1.
Highest Common Factor of 390,653,532 is 1
Step 1: Since 653 > 390, we apply the division lemma to 653 and 390, to get
653 = 390 x 1 + 263
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 263 and 390, to get
390 = 263 x 1 + 127
Step 3: We consider the new divisor 263 and the new remainder 127, and apply the division lemma to get
263 = 127 x 2 + 9
We consider the new divisor 127 and the new remainder 9,and apply the division lemma to get
127 = 9 x 14 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 390 and 653 is 1
Notice that 1 = HCF(9,1) = HCF(127,9) = HCF(263,127) = HCF(390,263) = HCF(653,390) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 532 > 1, we apply the division lemma to 532 and 1, to get
532 = 1 x 532 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 532 is 1
Notice that 1 = HCF(532,1) .
