GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(544, 778) = 211616
GCD(544, 778) = ( 544 x 778 ) / 211616
= 544 / 778
= 544
Step2:
LCM(2, 152) = 152
GCD(2, 152) = ( 2 x 152 ) / 152
= 2 / 152
= 2
Step3:
LCM(2, 642) = 642
GCD(2, 642) = ( 2 x 642 ) / 642
= 2 / 642
= 2
So, Greatest Common Divisor of 544, 778, 152, 642 is 2
