Given numbers are 861, 784, 363, 298
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 784) = 96432
GCD(861, 784) = ( 861 x 784 ) / 96432
= 861 / 784
= 861
Step2:
LCM(7, 363) = 2541
GCD(7, 363) = ( 7 x 363 ) / 2541
= 7 / 363
= 7
Step3:
LCM(1, 298) = 298
GCD(1, 298) = ( 1 x 298 ) / 298
= 1 / 298
= 1
So, Greatest Common Divisor of 861, 784, 363, 298 is 1
