Given numbers are 275, 130, 784, 357
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(275, 130) = 7150
GCD(275, 130) = ( 275 x 130 ) / 7150
= 275 / 130
= 275
Step2:
LCM(5, 784) = 3920
GCD(5, 784) = ( 5 x 784 ) / 3920
= 5 / 784
= 5
Step3:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
So, Greatest Common Divisor of 275, 130, 784, 357 is 1
