Given numbers are 238, 644, 989, 783

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

Apply this formula for all numbers.

Step1:

LCM(238, 644) = 10948

GCD(238, 644) = ( 238 x 644 ) / 10948

= 238 / 644

= 238

Step2:

LCM(14, 989) = 13846

GCD(14, 989) = ( 14 x 989 ) / 13846

= 14 / 989

= 14

Step3:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

So, Greatest Common Divisor of 238, 644, 989, 783 is 1
