Given numbers are 826, 530, 890, 639

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(826, 530) = 218890

GCD(826, 530) = ( 826 x 530 ) / 218890

= 826 / 530

= 826

Step2:

LCM(2, 890) = 890

GCD(2, 890) = ( 2 x 890 ) / 890

= 2 / 890

= 2

Step3:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

So, Greatest Common Divisor of 826, 530, 890, 639 is 1
