GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(362, 278) = 50318
GCD(362, 278) = ( 362 x 278 ) / 50318
= 362 / 278
= 362
Step2:
LCM(2, 665) = 1330
GCD(2, 665) = ( 2 x 665 ) / 1330
= 2 / 665
= 2
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 362, 278, 665, 820 is 1
