Given numbers are 380, 817, 220, 658
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(380, 817) = 16340
GCD(380, 817) = ( 380 x 817 ) / 16340
= 380 / 817
= 380
Step2:
LCM(19, 220) = 4180
GCD(19, 220) = ( 19 x 220 ) / 4180
= 19 / 220
= 19
Step3:
LCM(1, 658) = 658
GCD(1, 658) = ( 1 x 658 ) / 658
= 1 / 658
= 1
So, Greatest Common Divisor of 380, 817, 220, 658 is 1
