Given numbers are 644, 216, 133, 126
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 216) = 34776
GCD(644, 216) = ( 644 x 216 ) / 34776
= 644 / 216
= 644
Step2:
LCM(4, 133) = 532
GCD(4, 133) = ( 4 x 133 ) / 532
= 4 / 133
= 4
Step3:
LCM(1, 126) = 126
GCD(1, 126) = ( 1 x 126 ) / 126
= 1 / 126
= 1
So, Greatest Common Divisor of 644, 216, 133, 126 is 1
