Given numbers are 945, 393, 898, 697
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(945, 393) = 123795
GCD(945, 393) = ( 945 x 393 ) / 123795
= 945 / 393
= 945
Step2:
LCM(3, 898) = 2694
GCD(3, 898) = ( 3 x 898 ) / 2694
= 3 / 898
= 3
Step3:
LCM(1, 697) = 697
GCD(1, 697) = ( 1 x 697 ) / 697
= 1 / 697
= 1
So, Greatest Common Divisor of 945, 393, 898, 697 is 1
