Given numbers are 390, 202, 755, 970
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 202) = 39390
GCD(390, 202) = ( 390 x 202 ) / 39390
= 390 / 202
= 390
Step2:
LCM(2, 755) = 1510
GCD(2, 755) = ( 2 x 755 ) / 1510
= 2 / 755
= 2
Step3:
LCM(1, 970) = 970
GCD(1, 970) = ( 1 x 970 ) / 970
= 1 / 970
= 1
So, Greatest Common Divisor of 390, 202, 755, 970 is 1
