Given numbers are 115, 436, 955, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(115, 436) = 50140
GCD(115, 436) = ( 115 x 436 ) / 50140
= 115 / 436
= 115
Step2:
LCM(1, 955) = 955
GCD(1, 955) = ( 1 x 955 ) / 955
= 1 / 955
= 1
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 115, 436, 955, 649 is 1
