Given numbers are 218, 770, 805, 450
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(218, 770) = 83930
GCD(218, 770) = ( 218 x 770 ) / 83930
= 218 / 770
= 218
Step2:
LCM(2, 805) = 1610
GCD(2, 805) = ( 2 x 805 ) / 1610
= 2 / 805
= 2
Step3:
LCM(1, 450) = 450
GCD(1, 450) = ( 1 x 450 ) / 450
= 1 / 450
= 1
So, Greatest Common Divisor of 218, 770, 805, 450 is 1
