GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(102, 546) = 9282
GCD(102, 546) = ( 102 x 546 ) / 9282
= 102 / 546
= 102
Step2:
LCM(6, 784) = 2352
GCD(6, 784) = ( 6 x 784 ) / 2352
= 6 / 784
= 6
Step3:
LCM(2, 690) = 690
GCD(2, 690) = ( 2 x 690 ) / 690
= 2 / 690
= 2
So, Greatest Common Divisor of 102, 546, 784, 690 is 2
