Given numbers are 621, 906, 105, 436

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

Apply this formula for all numbers.

Step1:

LCM(621, 906) = 187542

GCD(621, 906) = ( 621 x 906 ) / 187542

= 621 / 906

= 621

Step2:

LCM(3, 105) = 105

GCD(3, 105) = ( 3 x 105 ) / 105

= 3 / 105

= 3

Step3:

LCM(3, 436) = 1308

GCD(3, 436) = ( 3 x 436 ) / 1308

= 3 / 436

= 3

So, Greatest Common Divisor of 621, 906, 105, 436 is 1
