Given numbers are 280, 639, 922, 370

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

Apply this formula for all numbers.

Step1:

LCM(280, 639) = 178920

GCD(280, 639) = ( 280 x 639 ) / 178920

= 280 / 639

= 280

Step2:

LCM(1, 922) = 922

GCD(1, 922) = ( 1 x 922 ) / 922

= 1 / 922

= 1

Step3:

LCM(1, 370) = 370

GCD(1, 370) = ( 1 x 370 ) / 370

= 1 / 370

= 1

So, Greatest Common Divisor of 280, 639, 922, 370 is 1
