Given numbers are 651, 378, 254, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(651, 378) = 11718
GCD(651, 378) = ( 651 x 378 ) / 11718
= 651 / 378
= 651
Step2:
LCM(21, 254) = 5334
GCD(21, 254) = ( 21 x 254 ) / 5334
= 21 / 254
= 21
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 651, 378, 254, 394 is 1
