Given numbers are 938, 105, 787, 830

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

Apply this formula for all numbers.

Step1:

LCM(938, 105) = 14070

GCD(938, 105) = ( 938 x 105 ) / 14070

= 938 / 105

= 938

Step2:

LCM(7, 787) = 5509

GCD(7, 787) = ( 7 x 787 ) / 5509

= 7 / 787

= 7

Step3:

LCM(1, 830) = 830

GCD(1, 830) = ( 1 x 830 ) / 830

= 1 / 830

= 1

So, Greatest Common Divisor of 938, 105, 787, 830 is 1
