Given numbers are 448, 430, 380, 661
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(448, 430) = 96320
GCD(448, 430) = ( 448 x 430 ) / 96320
= 448 / 430
= 448
Step2:
LCM(2, 380) = 380
GCD(2, 380) = ( 2 x 380 ) / 380
= 2 / 380
= 2
Step3:
LCM(2, 661) = 1322
GCD(2, 661) = ( 2 x 661 ) / 1322
= 2 / 661
= 2
So, Greatest Common Divisor of 448, 430, 380, 661 is 1
