Given numbers are 378, 152, 775, 490
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(378, 152) = 28728
GCD(378, 152) = ( 378 x 152 ) / 28728
= 378 / 152
= 378
Step2:
LCM(2, 775) = 1550
GCD(2, 775) = ( 2 x 775 ) / 1550
= 2 / 775
= 2
Step3:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
So, Greatest Common Divisor of 378, 152, 775, 490 is 1
