Given numbers are 749, 358, 861, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(749, 358) = 268142
GCD(749, 358) = ( 749 x 358 ) / 268142
= 749 / 358
= 749
Step2:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 749, 358, 861, 405 is 1
