HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 527, 781, 424, 921 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 527, 781, 424, 921 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, 781, 424, 921 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, 781, 424, 921 is 1.

HCF(527, 781, 424, 921) = 1

Highest Common Factor of 527,781,424,921 using Euclid's algorithm

Highest Common Factor of 527,781,424,921 is 1

Step 1: Since 781 > 527, we apply the division lemma to 781 and 527, to get

781 = 527 x 1 + 254

Step 2: Since the reminder 527 ≠ 0, we apply division lemma to 254 and 527, to get

527 = 254 x 2 + 19

Step 3: We consider the new divisor 254 and the new remainder 19, and apply the division lemma to get

254 = 19 x 13 + 7

We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get

19 = 7 x 2 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 527 and 781 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(254,19) = HCF(527,254) = HCF(781,527) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 424 > 1, we apply the division lemma to 424 and 1, to get

424 = 1 x 424 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 424 is 1

Notice that 1 = HCF(424,1) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 921 > 1, we apply the division lemma to 921 and 1, to get

921 = 1 x 921 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 921 is 1

Notice that 1 = HCF(921,1) .
