GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 757) = 485994
GCD(642, 757) = ( 642 x 757 ) / 485994
= 642 / 757
= 642
Step2:
LCM(1, 492) = 492
GCD(1, 492) = ( 1 x 492 ) / 492
= 1 / 492
= 1
Step3:
LCM(1, 844) = 844
GCD(1, 844) = ( 1 x 844 ) / 844
= 1 / 844
= 1
So, Greatest Common Divisor of 642, 757, 492, 844 is 1
