Given numbers are 380, 154, 661, 282
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(380, 154) = 29260
GCD(380, 154) = ( 380 x 154 ) / 29260
= 380 / 154
= 380
Step2:
LCM(2, 661) = 1322
GCD(2, 661) = ( 2 x 661 ) / 1322
= 2 / 661
= 2
Step3:
LCM(1, 282) = 282
GCD(1, 282) = ( 1 x 282 ) / 282
= 1 / 282
= 1
So, Greatest Common Divisor of 380, 154, 661, 282 is 1
