Given numbers are 915, 809, 981, 654
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(915, 809) = 740235
GCD(915, 809) = ( 915 x 809 ) / 740235
= 915 / 809
= 915
Step2:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
Step3:
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
= 1 / 654
= 1
So, Greatest Common Divisor of 915, 809, 981, 654 is 1
