GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(369, 915) = 112545
GCD(369, 915) = ( 369 x 915 ) / 112545
= 369 / 915
= 369
Step2:
LCM(3, 972) = 972
GCD(3, 972) = ( 3 x 972 ) / 972
= 3 / 972
= 3
Step3:
LCM(3, 785) = 2355
GCD(3, 785) = ( 3 x 785 ) / 2355
= 3 / 785
= 3
So, Greatest Common Divisor of 369, 915, 972, 785 is 1
