Given numbers are 945, 889, 689, 380

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

Apply this formula for all numbers.

Step1:

LCM(945, 889) = 120015

GCD(945, 889) = ( 945 x 889 ) / 120015

= 945 / 889

= 945

Step2:

LCM(7, 689) = 4823

GCD(7, 689) = ( 7 x 689 ) / 4823

= 7 / 689

= 7

Step3:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 945, 889, 689, 380 is 1
