Given numbers are 645, 800, 771, 882
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 800) = 103200
GCD(645, 800) = ( 645 x 800 ) / 103200
= 645 / 800
= 645
Step2:
LCM(5, 771) = 3855
GCD(5, 771) = ( 5 x 771 ) / 3855
= 5 / 771
= 5
Step3:
LCM(1, 882) = 882
GCD(1, 882) = ( 1 x 882 ) / 882
= 1 / 882
= 1
So, Greatest Common Divisor of 645, 800, 771, 882 is 1
