Given numbers are 133, 490, 764, 657
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(133, 490) = 9310
GCD(133, 490) = ( 133 x 490 ) / 9310
= 133 / 490
= 133
Step2:
LCM(7, 764) = 5348
GCD(7, 764) = ( 7 x 764 ) / 5348
= 7 / 764
= 7
Step3:
LCM(1, 657) = 657
GCD(1, 657) = ( 1 x 657 ) / 657
= 1 / 657
= 1
So, Greatest Common Divisor of 133, 490, 764, 657 is 1
