Given numbers are 861, 392, 204, 103
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 392) = 48216
GCD(861, 392) = ( 861 x 392 ) / 48216
= 861 / 392
= 861
Step2:
LCM(7, 204) = 1428
GCD(7, 204) = ( 7 x 204 ) / 1428
= 7 / 204
= 7
Step3:
LCM(1, 103) = 103
GCD(1, 103) = ( 1 x 103 ) / 103
= 1 / 103
= 1
So, Greatest Common Divisor of 861, 392, 204, 103 is 1
