Given numbers are 621, 682, 670, 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, 682) = 423522

GCD(621, 682) = ( 621 x 682 ) / 423522

= 621 / 682

= 621

Step2:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

Step3:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

So, Greatest Common Divisor of 621, 682, 670, 436 is 1
