GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(216, 738) = 8856
GCD(216, 738) = ( 216 x 738 ) / 8856
= 216 / 738
= 216
Step2:
LCM(18, 784) = 7056
GCD(18, 784) = ( 18 x 784 ) / 7056
= 18 / 784
= 18
Step3:
LCM(2, 639) = 1278
GCD(2, 639) = ( 2 x 639 ) / 1278
= 2 / 639
= 2
So, Greatest Common Divisor of 216, 738, 784, 639 is 1
