GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 684) = 73188
GCD(642, 684) = ( 642 x 684 ) / 73188
= 642 / 684
= 642
Step2:
LCM(6, 693) = 1386
GCD(6, 693) = ( 6 x 693 ) / 1386
= 6 / 693
= 6
Step3:
LCM(3, 114) = 114
GCD(3, 114) = ( 3 x 114 ) / 114
= 3 / 114
= 3
So, Greatest Common Divisor of 642, 684, 693, 114 is 3
