Given numbers are 220, 399, 402
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 399) = 87780
GCD(220, 399) = ( 220 x 399 ) / 87780
= 220 / 399
= 220
Step2:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
So, Greatest Common Divisor of 220, 399, 402 is 1
