Given numbers are 456, 306, 480, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(456, 306) = 23256
GCD(456, 306) = ( 456 x 306 ) / 23256
= 456 / 306
= 456
Step2:
LCM(6, 480) = 480
GCD(6, 480) = ( 6 x 480 ) / 480
= 6 / 480
= 6
Step3:
LCM(6, 861) = 1722
GCD(6, 861) = ( 6 x 861 ) / 1722
= 6 / 861
= 6
So, Greatest Common Divisor of 456, 306, 480, 861 is 3
